What to Wear to Pilates Class: A Reformer Instructor’s Honest Guide
From grippy socks to that sports bra dilemma — everything I tell my clients before their first session.
One of the most common questions I get — whether it’s a DM from someone in Sandy or a text from a friend in Lehi — is what to wear to Pilates class. It seems like it should be simple. And honestly, it mostly is. But there are a few things that genuinely matter, especially if you’re stepping onto a reformer for the first time. The wrong outfit won’t ruin your workout. But the right one? It lets you disappear into the movement. It removes one more thing to think about so you can focus on your breath, your alignment, your body waking up in ways it hasn’t before. I’ve been teaching reformer Pilates on the Wasatch Front for years, and I’ve seen every clothing choice imaginable roll through my studio doors. Let me save you the guesswork.
What to Wear to Pilates Class: The Quick Answer
Wear form-fitting, stretchy clothing that stays in place when you move. Think leggings (not loose joggers), a fitted tank or long-sleeve top, and grippy socks. Avoid zippers, buckles, loose jewelry, and anything baggy that could catch on reformer springs or obstruct your instructor’s view of your form. Comfort and function over fashion — always.
That’s the essentials in a nutshell. But there’s more nuance here than most people realize, especially for reformer Pilates versus a mat class. Let me break it down piece by piece.
Why Your Pilates Outfit Actually Matters on the Reformer
In a mat Pilates class, your clothing choices are pretty forgiving. You’re on the floor. Gravity is predictable. But a reformer is a different animal. You’re lying on a sliding carriage, your feet are in straps, your hands are gripping loops — and your body is moving through planes of motion that will test every stitch of fabric you’re wearing.
I see this with my clients at Alchemize Pilates all the time. Someone shows up in a flowy tank top, and by the time we’re doing overhead arm work, that top is around their neck. Or they’re in loose basketball shorts, and I can’t see whether their knees are tracking properly over their toes. It’s not about looking a certain way. It’s about me being able to teach you safely — and you being able to move without constantly adjusting your clothes.
The reformer also has metal hardware. Springs, hooks, the foot bar. Loose drawstrings and dangling jewelry can catch. It’s rare, but it happens. And it’s entirely avoidable.
The Best Bottoms to Wear to a Pilates Class
Leggings are queen. Full-length, high-waisted leggings in a moisture-wicking fabric are the gold standard. They stay put when you’re in a shoulder bridge. They don’t ride up when you’re in straps. And they let me see your leg alignment clearly.
Here’s what to look for:
- High waistband — so nothing slides down during inversions or roll-ups
- Compressive but not restrictive — you need full range of motion in your hips
- Squat-proof fabric — because you will be in compromising positions, and you deserve to feel confident
- No front seam that digs — comfort matters when you’re holding a teaser for what feels like an eternity
Bike shorts work great in warmer months too, especially during a Utah summer when even walking from your car in Draper feels like a sauna. Just make sure they’re mid-thigh length at minimum so they don’t bunch up.
What to skip: Loose joggers, sweatpants, anything with a drawstring that hangs loose, and jeans (yes, someone has tried). Also skip anything with external pockets or zippers — they press into the carriage padding and can scratch the reformer upholstery.
What to Wear on Top for Pilates
Fitted is the word here. You don’t need skin-tight — just something that stays where you put it.
My go-to recommendation: a fitted racerback tank, a cropped long-sleeve, or a snug performance tee. Anything that won’t flip over your head when you’re lying on your back doing footwork.
A few things I tell every new client who walks into my studio along the Wasatch Front:
- Avoid loose or drapey tops. They ride up. They obstruct my view. They’ll distract you.
- Layer if you tend to run cold. A fitted zip-up over your tank is fine — just take it off once you’re warm. Our studio stays comfortable, but I know some of you coming from Park City are perpetually cold.
- Sports bras matter. You don’t need high impact — Pilates isn’t plyometrics. A medium-support sports bra is perfect. Something that gives you confidence to move without constantly checking yourself. If you prefer just a sports bra as your top layer, that is absolutely welcome at Alchemize.
The Great Sock Debate: Grippy Socks for Pilates
This is where reformer Pilates diverges sharply from yoga and mat work. You need grippy socks.
Reformer Pilates is done in socks — not bare feet, not sneakers. The grip dots on the bottom of Pilates socks keep your feet from sliding on the foot bar, the carriage, and the platform. This isn’t optional. It’s a safety thing.
I keep a small selection of grippy socks available at the studio for clients who forget, but I always recommend investing in your own pair. They’re inexpensive — typically $8 to $18 — and they last a long time. Look for ones with grip on the entire sole, not just the toe area. Toeless or full-toe is personal preference; both work beautifully.

What Not to Wear to Pilates: The Things I Wish More People Knew
I say this with love and years of experience: there are a few things that actively get in the way of a good session.
- Long necklaces or dangly earrings. They get caught. They swing into your face. Leave them in the car.
- Watches and bulky fitness trackers. They press into your wrist during plank-based work and hand-in-strap exercises. A slim band is fine; a chunky smartwatch can be uncomfortable.
- Heavy perfume or cologne. This is a small, warm room. We’re breathing deeply. Please be mindful of the people around you.
- Clothes with exposed hardware. Metal zippers, decorative buckles, rivets — they scratch the reformer and dig into your body.
- Brand new, never-tested leggings. Try them at home first. Do a squat in the mirror. You want to discover opacity issues in your bathroom, not during a hundred on the carriage.
Do You Need Expensive Pilates Clothes?
No. Let me say it clearly: you do not need to spend a lot of money on Pilates clothing.
Some of the best-performing workout wear I’ve seen on my clients comes from Target, Amazon basics, Old Navy, and Costco. The $20 leggings from your last grocery run? If they fit well and stay put, they’re perfect.
What matters is the fit and the fabric, not the label. Look for polyester-spandex or nylon-spandex blends. They wick moisture, they stretch without losing shape, and they recover between washes. Cotton feels cozy, but it absorbs sweat and gets heavy. It also doesn’t move with you the way performance fabric does.
That said — if you love your Lululemon or your Alo Yoga, wear it with joy. The best Pilates outfit is the one that makes you feel good enough to stop thinking about what you’re wearing and start thinking about what your body is doing.
What to Wear to Pilates Class in Utah’s Unpredictable Weather
Utah is a place where you can experience three seasons in a single day. I have clients driving from Salt Lake City in rain, while my Cottonwood clients left their house in sunshine, and someone from Utah County is scraping frost off their windshield. This matters because what you wear to the studio and what you wear in the studio might be two different things.
My advice: dress in layers you can shed quickly. Arrive in your warm coat and boots if it’s January, but be ready to peel down to your leggings and tank once you step inside. I keep the studio warm enough that you’ll be comfortable from your first footwork set. And by mid-session, most of my clients are grateful they chose a breathable top.
In summer, bring a light layer anyway. Air conditioning plus deep breathing can leave you chilly during cool-down stretches.
What About Hair and Accessories?
A ponytail works — but be warned, it will press into the back of your head when you’re lying on the carriage. A low bun or a braid is more comfortable. High buns work if you don’t mind the occasional bump against the headrest.
Skip headbands that slide. Skip hats. Bobby pins can dig in. A soft scrunchie or claw clip is your best friend.
If you wear glasses, they’ll stay on for most exercises but may slide during anything where your head is below your heart. Contact lenses are easier for reformer work, but plenty of my clients wear glasses through the entire class without issue.
A Final Word: Wear What Lets You Move
At the end of the day, figuring out what to wear to Pilates class isn’t about perfection. It’s about removing friction — literal and figurative — so you can show up and do the work. Fitted leggings. A top that stays put. Grippy socks. That’s it. That’s the whole formula.
I’ve watched clients transform in my studio wearing everything from designer activewear to old college T-shirts (tucked in, of course). What they were wearing didn’t determine the quality of their practice. Their presence did. Their willingness to breathe, to shake, to try again — that’s what mattered.
If you’re getting ready for your first session, don’t overthink it. And if you want a full rundown of everything to expect beyond the wardrobe, read my first-timer’s guide for Utah beginners. I wrote it specifically so you can walk through our door feeling prepared, not nervous.
See you on the reformer.

Frequently Asked Questions About What to Wear to Pilates
Can I wear leggings with pockets to Pilates class?
Flat, sewn-in side pockets are usually fine. Avoid leggings with bulky cargo-style pockets or zipper pockets, as these can press into the reformer carriage and cause discomfort during lying exercises. If the pockets sit flat against your thigh, you’re good to go.
Do I really need grippy socks for reformer Pilates?
Yes. Grippy socks (also called Pilates socks or barre socks) are essential for reformer Pilates. The grip dots prevent your feet from sliding on the foot bar and platform, which is critical for safety and proper form. Most studios, including Alchemize Pilates, require them for every session.
Is it okay to wear just a sports bra to Pilates?
Absolutely. Many clients wear a sports bra as their top layer, and it’s completely welcomed at Alchemize Pilates. A medium-support bra is ideal — Pilates doesn’t involve high-impact jumping, so you don’t need maximum compression. Wear whatever allows you to move freely and feel confident.
Can I wear shorts to a Pilates reformer class?
Fitted bike shorts that hit mid-thigh or longer work well for reformer Pilates. Avoid loose or short athletic shorts — they ride up during leg strap work and can make it difficult for your instructor to see your knee and hip alignment. The key is that they stay in place during every movement.
What should I avoid wearing to my first Pilates class?
Avoid loose or baggy clothing, long necklaces, dangling earrings, clothes with zippers or metal hardware, and regular socks without grip. Also skip heavy perfume, as Pilates involves deep breathing in a small studio. Stick with fitted, stretchy activewear, grippy socks, and minimal accessories for the best experience.
