In your pilates era? These pilates outfits are perfect for mat, reformer or home workouts
Because matching set girls don't get tired 😉
Pilates has officially entered its main-character era – and so has the fashion that comes with it. Whether you’re flowing through a mat class, locked into a reformer session, or rolling out your mat at home, the right pilates outfit can make all the difference. Equal parts functional and stylish, today’s best pilates outfits are designed to support low-impact movement while still delivering on aesthetics, comfort, and confidence.
Thanks to the rise of studio culture, TikTok-fuelled “pilates princess” energy, and a new wave of fashion-conscious activewear brands, pilates clothing has evolved far beyond basic leggings and tanks. Think sculpting silhouettes, buttery-soft fabrics, breathable layers, and pieces you’ll happily wear straight from class to coffee. Because while pilates may be low impact, your outfit should still work hard – supporting your core, staying put through controlled movements, and allowing full freedom to stretch, twist, and extend.
In this edit, we’ve rounded up the best pilates outfits, grippy barre socks and fitness accessories for mat, reformer, and home workouts – focusing on styles that balance performance with aesthetics. From supportive sports bras and flattering leggings to elevated sets that feel as good as they look, these are the pilates outfits worth investing in now.
What is pilates?
Pilates is a low-impact workout that focuses on strength, flexibility, posture, and controlled movement – with a big emphasis on your core. Created by Joseph Pilates, it combines slow, intentional exercises with breathwork to build long, lean muscles and improve overall body awareness. Think fewer reps, more precision. Whether you’re working on a mat or using a reformer, pilates is designed to support everyday movement, making it accessible for beginners while still challenging enough to keep regulars coming back.
How we test the best pilates outfits
Every pilates outfit featured has been assessed by our Shopping Editor for comfort, support, and wearability during real mat and reformer workouts. We prioritised breathable fabrics, flexible fits that don’t restrict movement, and designs that stay in place from warm-up to cooldown – because nothing breaks focus faster than adjusting your kit mid-class.
Best Pilates Outfits & Matching Sets
The Ultimate Long Sleeve Top from Adanola is an easy win. Cut from a supportive four-way stretch fabric and a compressive longline fit, it hugs in all the right places without ever feeling restrictive – while the rich dark plum shade gives it that elevated, fashion-girl edge.
The Yosemite Top is exactly the kind of layering piece that elevates your whole look. Designed with a ballet-inspired wrap silhouette, long sleeves with thumb holes, and adjustable ties at the side, it adds softness and shape without getting in the way of movement.
A cult classic for a reason, lululemon’s Define Cropped Jacket is the kind of layer that works just as hard as you do. Cut in the brand’s signature Nulu fabric, it feels buttery-soft and weightless while still offering a sleek, sculpting fit that skims the body perfectly at the waist. Thumb holes keep sleeves in place during stretches, zipped pockets add everyday practicality, and the cropped length makes it ideal for throwing on over your pilates set pre- and post-class.
These Alo Yoga leggings land in the dreamiest, limited-edition Candy Heart Pink colourway – and it’s very much a wear-now-or-regret-later situation.
Cut from the brand’s Airbrush fabric with a soft, cottony feel and medium compression, it smooths and supports without ever feeling stiff. Style it head-to-toe with the matching top for a full pilates princess moment.
A personal favourite of Cosmo’s shopping editor, the AllTheForm™ Legging from Vuori is genuinely one of those pairs you look forward to wearing.
Crafted from the brand’s BlissBlendForm™ fabric, it delivers that ultra-buttery softness Vuori is known for, with just enough compression to feel supported without any restriction.
Comfy and ultra-flattering thanks to the high-rise waistband, it holds up beautifully in the wash and moves with you through every pilates or yoga flow. Once you try these, it’s hard to go back.
Best Pilates Grip Socks
A no-fuss essential that does exactly what it’s meant to. The Move anti-slip socks from H&M Move come in a handy two-pack and are designed with grippy soles to keep you steady through mat pilates and studio flows.
An absolute steal if you’re building out your pilates kit on a budget. This four-pack of cotton grip socks from BUDERMMY delivers serious value, with a soft, breathable feel and full-sole silicone grips for added confidence on the mat or reformer.
Balletcore, but make it studio-ready. This double-strap grip sock set from OYSHO brings a soft, fashion-forward twist to your pilates wardrobe, with crossover straps that feel straight out of a barre studio.
A cool-girl staple, courtesy of Adanola. Crafted from a soft organic cotton blend, they feature discreet silicone grips on the sole for added control during pilates and reformer sessions, plus a subtle embroidered logo for that low-key, considered feel.
A premium pick that delivers on both performance and polish, these grip socks from lululemon are worth the splurge if you want studio kit you can rely on.
Designed specifically for pilates and reformer work, they feature pressure-mapped grippers for a secure feel underfoot, plus breathable mesh panels and light cushioning for all-class comfort.
The supportive arch fit and left-right toe construction make them feel considered and technical, while the clean crew silhouette keeps things effortlessly cool.
A practical two-pack that doesn’t skimp on comfort, the Reformer Trainer Gripper Socks from Sweaty Betty are designed with studio sessions in mind.
Made from a soft organic cotton blend, they feature a wraparound gripper panel to help you feel secure on the reformer or mat, while built-in arch support and an anti-blister heel panel make longer classes far more comfortable.
Best Pilates Workout Accessories
Bala Bangles add just enough resistance to level up your pilates routine without disrupting your flow. Wrapped in baby-soft silicone with a flexible, adjustable fit, they feel comfortable whether worn on your wrists or ankles.
Perfect for pilates, barre, walks, or even adding subtle strength work to everyday movement, they’re a simple way to make low-impact workouts work harder. Available in sage, classic black, or soft pink, they also happen to look very good while doing it.
A pilates ring – or magic circle – is a simple and effective way to level-up home and studio workouts. It’s designed to add controlled resistance for arms, thighs, core, glutes, and pelvic floor work, helping improve strength, posture, and muscle control.
The dual foam handles make it comfortable to grip and easy to use between hands, thighs, or ankles, while the compact size means it’s ideal for travelling or small-space workouts. Available in classic black or playful pastel shades, it’s a practical pick that earns its place in your pilates kit.
A smart add-to-bag moment while they’re 20% off. This resistance bands set is ideal for pilates, home workouts, and glute-focused sessions, with three different resistance levels so you can tailor the burn to your mood (and muscle group).
Made from durable fabric with a non-slip inner layer, they stay put through squats, bridges, and leg work without rolling or pinching. The varying lengths add versatility, while the compact carry bag makes them easy to throw in your kit for studio days or travel.
Who knew OYSHO was quietly nailing fitness essentials too? This 5mm yoga mat proves exactly why the brand has fast become a go-to for affordable, well-designed pilates kit.
It offers just the right amount of cushioning for beginner-friendly mat and pilates sessions, while the subtle placement design helps guide hand and foot positioning as you move.
