Booking your first reformer Pilates class is exciting and slightly nerve-wracking. A lot of first-timers worry more about wearing the wrong thing than about the workout itself. The reformer is a moving machine with springs, straps and a sliding carriage, so what you wear genuinely affects how safe, comfortable and confident you feel. Here is a simple, no-stress guide to exactly what to wear to your first reformer Pilates class, from head to toe.
Why reformer clothing is different
Reformer Pilates has stricter clothing needs than most fitness formats, and for good reason. The machine has moving parts that loose fabric can catch on. Many exercises are done lying down or upside down, so anything baggy will slide toward your face. And your instructor needs a clear view of your alignment to keep you safe and correct your form. The golden rule: fitted, stretchy and secure.
The footwear question: grip socks or bare feet?
This is the part beginners most often get wrong. The vast majority of reformer studios across Europe require grip socks - they are not optional, and here is why:
- Safety. The carriage and footbar can be slippery, especially during footwork and standing work. Grip socks give you traction so you can focus on form instead of fighting to stay put.
- Hygiene. Bare feet on shared equipment is a no-go in most professional studios. Grip socks keep things clean for everyone.
Some studios sell socks at the desk for a premium, so it's worth bringing your own pair. Look for full-foot grip coverage (not just a few dots at the toes), a snug fit that won't twist mid-plank, and breathable fabric. Buying ahead of time means you walk in prepared rather than getting caught out at check-in.
What to wear on top
Choose a fitted, breathable top that stays put when you lie down or invert. A snug tank, fitted tee, or a supportive sports bra with a light long-sleeve all work well. Avoid loose tees that ride up and block your view. A medium-support sports bra is ideal: enough to feel secure, without digging in during the slower, controlled movements.
What to wear on the bottom
High-waisted leggings are the reformer standard for a reason as they stay in place through every roll, stretch and leg-in-strap movement. Fitted capris or longer bike shorts also work. Look for a flat, secure waistband that won't fold over, and fabric with enough opacity that you feel covered in every position. If you run warm, moisture-wicking fabric keeps you comfortable through a full-body flow.
What to avoid
- Loose or baggy clothing --> it can catch in the springs and hides your alignment.
- Zips, buttons, buckles and embellishments --> these can scratch the carriage or dig into you when lying down.
- Regular trainers or shoes --> never worn on a reformer.
- Plain regular socks --> they're slippery and unsafe on the carriage.
- Chunky jewellery and watches --> leave them at home or in your locker.
What to bring to your first class
Beyond your outfit, you need very little:
- Grip socks: the one essential most studios require.
- A water bottle: reformer work is more demanding than it looks.
- A small towel: handy for sweat, especially in warmer studios.
- A hair tie: you'll be lying on the back of your head, so a low ponytail or bun keeps you comfortable.
- A light removable layer: your body warms up quickly once footwork begins.
Arrive 10 to 15 minutes early so you can check in, stash your things, and let your instructor know it's your first class. They'll show you how to get on and off the machine, set the springs, and offer modifications.
