All bodies are unique and our mission is to produce swimsuits that celebrate all body types. That’s why it’s so important to us that our fit is as accurate as possible. With this in mind, we have included a “Find My Size” feature on each product page so that we can recommend the perfect size based on your individual measurements.
HOW TO MEASURE
Bust: measure around the fullest part of your bust.
Underbust: measure snugly around your ribcage, just under your bust.
Waist: measure around the narrowest part of your waist.
Hips: measure around the fullest part of your hips and bottom, feet together.

BETWEEN SIZES?
Tops: choose by your underbust measurement. If you’re between sizes, size down for a more secure, supported fit. If you have a fuller bust, see Finding your cup fit below.
Bottoms: for styles that sit on the hip, choose by your hip measurement. Size up for more coverage, or down for a snugger, cheekier fit.
One pieces: if your top and bottom measurements fall in different sizes, choose the larger size, as a one piece needs room through the body as well as the bust. If you have a Small body with a C or D cup, choose S+ where available.
FINDING YOUR CUP FIT
XS to XL are cut for an A to C cup. If you’re a C or D cup with a Small underbust, our S+ is made for you: it has the same band as a Small, with a fuller cup and longer underwire. For a D cup or above in any other size, we recommend our adjustable or tie styles.
BOTTOM COVERAGE VARIES BY STYLE
From cheeky to full, each style sits a little differently. Check the fit notes on each piece before choosing your size.
ONE PIECES
If you’re 170cm or taller, or have a longer torso, check the fit notes on each style before choosing your size.
MIX YOUR SIZES
Tops and bottoms are sold separately, so you can choose a different size for each.
