Fit Guide

Here to support you in all the ways, always.

The Perfect Fit

And that means designing for real bodies, not just mannequins. Our swimsuits blend innovative design with an impeccable fit that supports, shapes, and flatters every body — from long torso and plus size options to mastectomy-friendly and beyond.

BUST

Measure the fullest part of your bust, keeping the tape measure parallel to the floor.

WAIST

Standing tall, wrap the tape measure around the natural crease of your waist.

HIPS

With your heels together, measure around the widest part of your lower hips (usually 7–8 inches below the waist).

TORSO

With help, hold a tape measure at your shoulder and let it drop down your back. Pull it between your legs and up across the fullest part of your bust.

A Fit That 
Feels Different

We’ve spent 30+ years perfecting our flawless fit — and we’ve got the expertise to prove it. Our team 
of pros knows exactly what works, what flatters, 
and what feels amazing.

Fit That Feels Right

When it fits well, it feels amazing.
Here’s how to make sure your swimsuit fits like a dream.

Straps

Can you slip a thumb under the strap comfortably? If not, size up. If the straps slip off, try sizing down or exploring another style.

Back

Riding up or bulging? 
Try a different style or size up. 
Loose or sagging? Size down.

Bra

Your bust should fill the cups. Gapping or lack of support? 
Go smaller or try another style.

Crotch

Check for a comfortable fit. If the suit is cutting in, bulging, or riding up, try a different style or size. If it's sagging or feels loose, try a smaller size.

Underarm

Ensure everything’s smooth around the underarms. If you're noticing pinching, bulging, or riding up, go for a different style or size. If it feels too loose, try a smaller size.

Derriere

Check coverage. If the suit is digging in or riding up, try a larger size or different cut. For sagging or loose fits, consider a smaller size.

Pro tip: Move around! Lift your arms, twist, bend, squat... a great fit stays put (and feels good through it all).
