What to Wear to Reformer Pilates: A UK Beginner’s Checklist
Your first Reformer Pilates class is booked. You know there will be springs, straps and a moving carriage involved, but what exactly should you wear to Reformer Pilates?
The good news is that you don't need a completely new wardrobe to get started. The best Reformer Pilates outfit is comfortable, close-fitting, flexible and designed to move with your body rather than against it.
For most women, that means high-waisted Pilates leggings or fitted shorts, a supportive sports bra, a fitted vest or top and a pair of grip socks. Add a light layer for travelling to and from the studio and you have everything you need.
However, there are a few details worth getting right. Reformer Pilates involves controlled movements in a wide range of positions, so clothing that feels perfectly comfortable for walking or going to the gym may become distracting once you're lying on the carriage, extending your legs or moving through a sequence.
This UK beginner's guide explains what to wear to your first Reformer Pilates class, what not to wear, whether you need grip socks and what features to look for when choosing Pilates activewear.
The Quick Reformer Pilates Clothing Checklist
Before your first class, check that you have:
- High-waisted, close-fitting leggings or fitted Pilates shorts
- A comfortable, supportive sports bra
- A fitted vest, tank or activewear top
- Grip socks if required by your studio
- A light jumper, jacket or layer for before and after class
- Hair tied back if it is long
- Minimal jewellery
- A water bottle
- Clothing that passes the stretch, bend and squat test
That's really all you need.
The most important principle is simple: wear activewear that allows unrestricted movement without excess fabric getting in the way.
Current UK Reformer Pilates guidance similarly recommends comfortable, relatively close-fitting clothing because loose material can interfere with equipment and fitted clothing can make it easier for an instructor to see your movement and alignment.
“For Reformer, I always recommend clothing that stays in place and lets you move freely. You don't want to be adjusting your leggings or top halfway through a movement.”
— Beth Carden, Reformer Pilates Instructor.

Why Does What You Wear to Reformer Pilates Matter?
Reformer Pilates is different from simply doing a workout on a mat.
A Reformer uses a sliding carriage, springs, straps, footbars and other moving components. During a typical class you may be lying on your back, kneeling, standing, extending your legs, rotating your body and moving through controlled positions.
Your clothing therefore needs to do three things particularly well:
Move. Stay in place. Stay out of the way.
You don't necessarily need specialist clothing labelled "Reformer Pilates wear", but well-designed Pilates activewear can make your session considerably more comfortable.
Ideally, you should be able to concentrate on your instructor and your movement rather than pulling up your waistband, adjusting your top or worrying whether your leggings have become transparent as the fabric stretches.
1. Choose Leggings That Stay in Place
For most women, full-length or 7/8 high-waisted leggings are one of the best choices for Reformer Pilates.
They provide coverage without loose fabric and allow your legs to move freely through flexion, extension and rotation.
But not all gym leggings perform equally well during Pilates.
Look for four-way stretch
Reformer Pilates involves movement in several directions, so your leggings should stretch both horizontally and vertically.
A good four-way stretch fabric should move with your hips and legs without feeling restrictive or requiring constant adjustment.
Choose a secure high-rise waistband
Few things are more irritating during a Pilates class than repeatedly pulling your leggings back up.
A comfortable high-waisted Pilates legging can provide a secure feel around the waist while allowing you to bend and rotate naturally.
The waistband should feel supportive without digging painfully into your stomach.
Prioritise coverage
You'll spend part of a Reformer class in positions you probably don't encounter walking around the supermarket.
That makes reliable coverage particularly important.
Before wearing new leggings to class, try this simple test at home:
- Stand in good natural light.
- Perform a deep squat.
- Bend forward.
- Raise each knee towards your chest.
- Check the rear of the fabric in a mirror or using your phone camera.
If you're comfortable with the coverage, you're far less likely to think about it during class.
The sustainable option: Cloud Fit™
For women looking for sustainable Pilates leggings in the UK, Sleepy Sloth's Cloud Fit™ leggings have been designed specifically around softer, controlled movement including yoga and Pilates.
Cloud Fit™ combines a high-rise fit, four-way stretch, medium compression and squat-proof coverage with a soft recycled performance fabric.
The fabric composition is 82% recycled polyester and 18% spandex, making Cloud Fit™ particularly relevant for anyone looking to combine performance with a more considered approach to activewear.
The result is the kind of legging we believe Reformer Pilates needs: supportive enough to stay in position, but without the heavy compression often associated with high-impact gymwear.
2. Wear a Comfortable Sports Bra
Do you need a sports bra for Pilates?
For most women, yes, but you generally don't need the same level of support you might choose for running or high-impact exercise.
Reformer Pilates is typically controlled rather than high-impact, so comfort and freedom of movement are particularly important.
Look for:
- A secure underband
- Comfortable shoulder straps
- Soft stretch fabric
- Enough support for your individual bust size
- A design that doesn't dig in when lying on your back
- Freedom through the shoulders and upper body
Extremely rigid bras can sometimes feel unnecessary for slower controlled movement.
At the other extreme, a fashion bralette may not provide enough security as you change positions.
The ideal Pilates sports bra sits comfortably somewhere between the two.
Sleepy Sloth's Cloud Fit™ Sports Bra uses the same 82% recycled polyester and 18% spandex fabric as the matching leggings and is designed with medium support, stretch and lightweight comfort for activities including Pilates and yoga.
Pairing the bra and leggings also creates an easy matching Reformer Pilates set without compromising the practical requirements of the session.
3. Choose a Fitted Top Rather Than an Oversized T-Shirt
You absolutely can wear a T-shirt to Pilates.
However, beginners often discover why fitted Pilates tops and racerback vests are so popular once they start moving.
An oversized T-shirt can fall towards your face when bending, twisting or performing movements where your hips are elevated.
Loose fabric can also make it harder for your instructor to see your posture and alignment.
A fitted vest, cropped activewear top or close-fitting T-shirt is therefore usually easier.
Look for a top that:
- Stretches with your body
- Doesn't ride up excessively
- Allows unrestricted shoulder movement
- Feels breathable
- Doesn't have bulky zips, buckles or hardware
If you prefer more coverage, simply choose a longer fitted top rather than going oversized.
Comfort should always win over following a particular Pilates aesthetic.
4. Do You Need Grip Socks for Reformer Pilates?
One of the most searched beginner questions is:
Do you need grip socks for Reformer Pilates?
The answer depends on the studio.
Some UK studios require grip socks for Reformer classes, while others recommend them. For example, Ten Health & Fitness currently requires grip socks for its Reformer Pilates sessions.
So before your first class, check the individual studio's policy.
Grip socks have small grippy sections underneath the foot designed to provide additional traction.
They can be useful when your feet are positioned on the carriage, platform or other surfaces and also provide a barrier between your feet and shared studio equipment.
If your studio requires them and you've forgotten yours, some studios sell pairs at reception.
The safest option is simply to check before you arrive.
5. Leggings or Shorts for Reformer Pilates?
Both can work extremely well.
The choice between Pilates leggings and Pilates shorts mostly comes down to personal comfort, studio temperature and the amount of coverage you prefer.
Pilates leggings are ideal if you want:
- Full leg coverage
- Warmth during cooler months
- Minimal skin contact with equipment
- A smooth, streamlined fit
- More confidence in different Pilates positions
Pilates shorts are ideal if you:
- Tend to become warm during class
- Prefer less fabric
- Attend heated or particularly warm studios
- Simply feel more comfortable training in shorts
If wearing shorts, fitted cycling-style or Pilates shorts are usually more practical than loose running shorts.
Loose shorts can shift significantly when your legs are raised.
For Reformer Pilates, a close-fitting pair with good stretch provides much greater confidence and freedom of movement.
6. What Should You Avoid Wearing to Reformer Pilates?
There is no strict Pilates fashion rulebook.
But certain garments can become inconvenient around Reformer equipment.
Very loose trousers
Wide-leg trousers and excessively loose jogging bottoms may move around, obscure your legs or potentially get close to moving parts of the equipment.
This doesn't mean Reformer Pilates requires skin-tight clothing, but a closer fit is generally more practical.
Clothing with bulky zips and hardware
Think about the positions you'll be lying in.
A large zip positioned across your back might look great standing up but feel considerably less appealing when you're lying on it for 15 minutes.
Avoid unnecessary:
- Zips
- Buckles
- Large buttons
- Hard decorative pieces
- Bulky pockets
Leggings that constantly slide down
If you're already pulling your leggings up while walking around the house, a Reformer session probably won't improve matters.
The correct size and waistband construction matter.
Restrictive clothing
Pilates requires considerable freedom through the hips, shoulders and spine.
Anything that prevents you moving comfortably is probably the wrong choice.
Jewellery that can catch
Large necklaces, bracelets and dangling jewellery are best left in your bag.
Long hair should also be secured where practical.
7. What Fabric Is Best for Reformer Pilates Clothing?
There isn't one single "best" Pilates fabric.
Instead, think about the properties you need.
Good Reformer Pilates activewear should ideally offer:
Stretch
Your clothing needs to accommodate deep hip and knee flexion without fighting against your movement.
Recovery
Stretch is only half of the equation.
The fabric also needs to recover its shape rather than gradually becoming loose throughout the class.
Breathability
Reformer Pilates may look controlled from the outside, but a challenging session can still generate considerable body heat.
Lightweight activewear tends to be more comfortable.
Softness
Reformer involves significant floor and equipment contact, making soft fabrics especially pleasant for longer sessions.
Durability
Sustainable activewear isn't simply about what a garment is made from.
How long you can comfortably use it matters too.
Choosing clothing that performs consistently and caring for it correctly can help extend its useful life.
8. Can Sustainable Activewear Perform Properly in Pilates?
Absolutely, provided the garment has been designed for performance rather than relying on sustainability as a marketing label.
This distinction matters.
At Sleepy Sloth, we don't believe women should have to choose between comfortable performance activewear and more responsible materials.
Our Cloud Fit™ leggings, for example, use recycled performance fibres while retaining the stretch, softness, medium compression and coverage needed for Pilates and everyday movement.
Sleepy Sloth also offers Power-Fit Pilates leggings made using 68% recycled polyamide and 32% Creora® elastane, with four-way stretch and a sculpting second-skin feel.
When comparing sustainable Pilates clothes, don't simply look for the word "eco".
Look at:
- The actual fabric composition
- Whether recycled materials are identified
- Relevant textile certifications
- Garment construction
- Durability
- Packaging
- Whether the brand explains its claims rather than relying on vague environmental language
A garment still has to perform.
Sustainability shouldn't be an excuse for compromising on comfort.
9. What Should You Wear to Reformer Pilates in Winter?
UK weather creates an additional problem that many international Pilates guides ignore.
The studio might be warm.
The walk back to your car definitely might not be.
The easiest solution is layering.
Wear your normal Reformer Pilates outfit underneath:
- A lightweight sweatshirt
- Zip jacket
- Oversized hoodie
- Warm coat
- Comfortable trainers
Then remove your outer layers once you're inside the studio.
You don't need to exercise wearing everything you arrived in.
Likewise, taking a warm layer for immediately after your session can make the journey home considerably more comfortable.
10. What Should You Wear to Reformer Pilates in Summer?
In warmer weather, simplify things.
A lightweight sports bra or fitted vest combined with leggings or cycling-style shorts is usually sufficient.
Prioritise breathable, flexible fabrics and avoid unnecessary layers.
If you're walking to the studio, a loose shirt or lightweight jacket over your activewear provides an easy additional layer that can be removed before class.
What to Bring to Your First Reformer Pilates Class
Clothing sorted?
Your bag for your first class doesn't need much else.
Consider taking:
- Water bottle — particularly useful after a challenging session.
- Grip socks — if required or recommended by your studio.
- Small towel — check whether your studio provides one.
- Hair tie — easy to forget and surprisingly useful.
- Light layer — particularly during colder UK weather.
It's also worth arriving slightly early for your first session.
At least one major UK Reformer operator recommends beginners arrive around 10 minutes early so the instructor can explain the equipment and help them get set up.
The Three-Minute Reformer Pilates Outfit Test
Before leaving home, put on your complete outfit and perform these simple movements.
The squat test
Squat as deeply as is comfortable.
Do your leggings remain opaque and does the waistband stay in position?
The overhead reach
Raise both arms overhead.
Does your top remain where you want it, or does it ride halfway up your torso?
The knee-to-chest test
Bring one knee at a time towards your chest.
Do your leggings move comfortably through the hips without pulling down at the waist?
If your clothing passes all three, you're probably ready.
Your Pilates outfit shouldn't be something you spend your entire Pilates class thinking about.
What Should a Beginner Wear to Reformer Pilates?
For your first Reformer Pilates class, keep things straightforward:
High-waisted leggings + comfortable sports bra + fitted top + grip socks where required.
That's it.
Don't worry about arriving in the latest Instagram Pilates outfit.
Your instructor is far more interested in helping you move correctly than which brand you're wearing.
The purpose of good activewear is actually the opposite of attracting your attention.
When it's doing its job properly, you almost forget about it.
It stretches when you move.
It stays in position.
It provides the coverage you expect.
And it allows you to concentrate on the class.

Reformer Pilates Clothing FAQs
Can I wear normal gym clothes to Reformer Pilates?
Yes. Normal gym clothing can be perfectly suitable for Reformer Pilates if it is comfortable, flexible and reasonably close-fitting. Avoid excessively loose garments and bulky hardware that could become uncomfortable or interfere with the equipment.
Can I wear leggings to Reformer Pilates?
Yes. Stretchy, close-fitting leggings are one of the most popular options for Reformer Pilates because they provide freedom of movement while reducing excess fabric around the equipment.
What leggings are best for Reformer Pilates?
Look for high-waisted Pilates leggings with four-way stretch, reliable coverage, good fabric recovery and a waistband that remains comfortably in position during bending and controlled movement.
Do I need special Pilates leggings?
No. You don't need clothing specifically labelled "Pilates leggings". However, leggings designed for flexible, low-impact movement can offer a better balance between stretch, softness and comfortable support than heavily compressive training leggings.
Should Pilates leggings be tight?
They should fit close enough to stay in position without feeling painfully restrictive. Wrinkling, sliding or excessive fabric movement may indicate they are too large, while severe digging, restricted movement or excessive stretching of the fabric can indicate they are too small.
Do you need a sports bra for Reformer Pilates?
Most women find a sports bra more comfortable and supportive during Reformer Pilates. Because Pilates is generally low impact, many people prefer light-to-medium support rather than the high-impact support used for running.
Do you need grip socks for Reformer Pilates?
It depends on your studio. Some UK studios require grip socks while others simply recommend them, so check before your first class.
Can you do Reformer Pilates barefoot?
Studio policies vary. Some Pilates environments allow barefoot exercise, while others require socks or grip socks for Reformer sessions. Always follow your studio's individual policy.
Can I wear shorts to Reformer Pilates?
Yes. Fitted cycling-style or Pilates shorts can work very well, particularly in warmer studios. Choose a length and level of coverage that leaves you comfortable when lying down and lifting your legs.
Can I wear flared leggings to Reformer Pilates?
You can, but very wide flares create more loose fabric around the lower leg than conventional fitted leggings. For a first Reformer class, close-fitting leggings are generally the simpler and more practical option.
Can I wear an oversized T-shirt to Pilates?
You can, but it may fall towards your face or move considerably when bending and changing position. A fitted top or vest is often easier for Reformer Pilates.
What should I wear to my first Pilates class in the UK?
For a beginner Reformer class, wear comfortable leggings or fitted shorts, a sports bra, a fitted activewear top and grip socks if required. In cooler UK weather, add a warm outer layer for travelling to and from the studio.
What is the best sustainable activewear for Reformer Pilates?
Look beyond environmental buzzwords and choose sustainable activewear that still provides the technical features Pilates requires: stretch, coverage, comfort, fabric recovery and a secure fit. Recycled-material leggings such as Sleepy Sloth Cloud Fit™ combine these performance features with recycled fibres.
