Match your bust and hip below. If they land in different sizes, go with the larger size — a one-piece has to fit both.

About the fit

True to size, with a structured, sculpting hold. This suit is cut from Eco Sparkle, a shimmery recycled-nylon knit woven through with metallic silver thread and fully lined in soft recycled mesh. It has a touch less give than typical swim — that structure is exactly what holds and sculpts the torso — so measuring accurately matters a little more here than on our stretchier pieces. One care note: rinse it in fresh water after pool days to keep the metallic shimmer at its best.

A one-piece fits your torso first. The fabric stretches around your bust, waist, and hip — but torso length doesn't stretch. If one-pieces usually feel short on you (pulling at the shoulders, riding up), that's a long torso: go up a size. Shorter through the torso? Stay true to size — the straps take up the slack.

The straps adjust through the gold rings. Longer torso? Let the straps out. Shorter torso? Take them in. The open back gives the fit room to flex either way.

Between sizes? Size up. The fabric will smooth a roomier fit, but it can't add length or inches where it's snug. And don't size down for a tighter hold — the sculpt comes from the fabric's structure, not from squeezing into a smaller size.

How to measure

• Bust: around the fullest part, tape level, no squeeze.
• Waist: around the narrowest point, usually just above the navel.
• Hip: around the fullest part of your hips and seat, about 8" below your waist.
• Torso (the tiebreaker): run the tape from the top of one shoulder, down your front, through your legs, and back up to the same shoulder. No chart number needed — just know your lean: long torso, size up; short torso, true to size and adjust the straps. Or skip the tape entirely and use the garment measurements below.

Garment Measurements (Laid Flat)

The compare-with-your-favorite method. These are this suit's own measurements, laid flat. Lay a one-piece that already fits you well next to these numbers — front length is the torso tiebreaker. One thing: don't double the width against your bust. Swim fabric is cut smaller than the body on purpose and stretches past these numbers when worn — the bust/waist/hip chart above is what picks your size; the lengths are what settle torso doubts.

Front width — across the front at the underarm · Front length — top edge to gusset, down the front · Back length — top edge to gusset, down the open back.
