Pilates has exploded in popularity — mat classes, reformer studios, and aerial pilates now attract practitioners of every fitness level. But what you wear to a mat pilates class in a park is quite different from what works on a reformer machine in a heated studio.
Mat Pilates
Mat pilates involves floor-based sequences — rolling, bridging, leg circles, and core work. You'll be lying on your back, sides, and stomach, as well as kneeling and standing. The priorities:
- Form-fitting through the torso: Loose shirts fall over your face during ab work. A fitted tank or sports bra helps instructors check your form and prevents distraction.
- Opaque leggings: You'll be in positions where opacity is essential. SisFlow™ leggings are specifically engineered to be squat-proof at any angle.
- No waistband bulge: A flat, wide waistband is more comfortable during floor-based core work than a narrow elastic band.
SISQUEEN picks: SisFlow™ High-Waist Leggings + SisFlow™ Cami Bodysuit. The bodysuit tucks into the leggings for seamless coverage throughout the session.
Reformer Pilates
Reformer pilates adds resistance and sliding motion to the classical Pilates movements. You'll be in socks (grip socks are often required), lying on the carriage, kneeling, and standing. Key differences from mat work:
- Grip socks are essential: Reformer studios require grip socks for safety on the moving carriage. Check your studio's requirements before your first class.
- Fitted from ankle to waist: Loose fabric can catch on the reformer footbar or straps. Full-length, fitted leggings are the standard.
- Light layering: Studios vary in temperature. A fitted long-sleeve layer you can remove is useful.
SISQUEEN picks: SisFlow™ Full-Length Leggings + SisFlow™ Long Sleeve + Light Open-Back Sports Bra underneath.
Aerial and Suspension Pilates
Aerial pilates uses fabric hammocks or TRX straps for suspended movements. The hammock contacts your body directly, so avoid metal hardware, rough textures, or protruding seams that could damage the equipment or catch during movement.
- Choose smooth-surface fabrics — SisFlow™ is ideal.
- Avoid waistbands with zippers or thick seams at the back.
- Long-sleeve tops protect arms and underarms from hammock contact.
What to Avoid in Pilates
- Baggy tops or drawstring hoodies: They fall over your face in supine positions and can catch on equipment.
- Shorts shorter than 6": In many pilates positions, short shorts provide insufficient coverage.
- Hard-soled shoes: Pilates is typically practiced barefoot or in grip socks. Most studios prohibit shoes on equipment.
Frequently Asked Questions
What should I wear to a reformer pilates class?
Fitted, full-length leggings in a smooth, opaque fabric are the standard for reformer pilates. SISQUEEN's SisFlow™ leggings work well — they're squat-proof, smooth-surfaced, and won't catch on the reformer. Pair with a fitted tank or long-sleeve top and bring grip socks.
Do I need special socks for pilates?
For reformer pilates, grip socks with non-slip rubber dots on the sole are required at most studios for safety. For mat pilates, bare feet are fine. Grip socks are available at most reformer studios or can be purchased in advance.
Can I wear a bodysuit to pilates?
Yes — bodysuits are one of the best choices for pilates because they stay tucked in regardless of position. SISQUEEN's SisFlow™ Cami Bodysuit pairs perfectly with high-waist leggings for seamless coverage during floor work and inversions.
Is there a difference between yoga and pilates activewear?
The requirements are very similar — both benefit from fitted, opaque, four-way stretch fabric. The main pilates-specific consideration is smooth fabric surface (especially for reformer work) and avoiding metal hardware or rough textures that could damage equipment. SisFlow™ is ideal for both.
What fabric is best for pilates?
Soft, smooth, four-way stretch fabric with good opacity is best for pilates. SISQUEEN's SisFlow™ series was designed with low-impact movement in mind — it moves with the body without shifting, maintains opacity in all positions, and is gentle enough for extended floor work.
