Use chest, waist and hip, not your legging size.
Between sizes? Size up
The fit is snug and sculpted by design.

01
Step in

02
Pull up over the hips
Work it up over the hips; this is the snug part.

Adjust into place
Settle the shorts, waist and corsetry where they belong.

Fits like a glove
Once on, it's sculpted with excellent freedom of movement.
Good to know: the pull over the hips is the snug moment. It's normal, and it's what makes the fit.

FIT GUIDETHE BUILT-IN SHORTS
Stay put
Elastane leg openings help prevent riding up and minimize chafing.
A gentle hold
Some women notice the hold at first. It isn't designed to pinch and takes a moment to get used to.
The secret to the silhouette
The shorts anchor the corsetry, creating our signature sleek, sculpted shape.
YES, IT'S ASKED A LOT
Because it's a one-piece, the dress comes off to use the restroom. It's the trade-off for the sculpted fit.
