Find Your Perfect Fit
All measurements below are body measurements. Take your time — the right fit makes all the difference.
Bust
Standing tall, measure loosely around the fullest part of your bust, keeping the tape parallel across your back.
Underbust
Around your ribcage, just under your bust. Tape snug and parallel across your back. Wear a non-padded bra for this one.
Waist
At the smallest part of your waist, measure loosely with the tape parallel to the floor.
Hips
At the fullest part of your hips and seat, keep the tape parallel all the way around your body.

Product details
Product details
The shaper short that never rolls down. StayPut™ combines ultra-soft comfy compression with an anti-slip grip waistband that stays exactly where you put it — all day, every wear. Smooths your tummy, slims your thighs, lifts your curves and vanishes under skirts, dresses and fitted pants.
Why you'll love it
- No roll-down. Ever. Anti-slip grip technology built into the high waistband keeps it locked in place while you move.
- Super comfy compression. Signature ultra-soft fabric flattens the mid-to-lower tummy without squeezing or digging.
- Natural butt-lift effect. A ruched back seam rounds and lifts, no padding.
- Smooths thighs & hides cellulite. High-coverage mid-thigh leg slims your silhouette and blurs texture under thin fabrics.
- Zero chafing. The perfect layer under skirts and dresses to stop thigh rub.
- Truly invisible. Seamless knit + laser-cut leg bands: no lines under bodycon dresses or fitted pants.
Fabric
50% elastane, 50% polyamide. Second-skin stretch, ultra light for all-day wear.
