Sizing Guide
Our bikini tops and bottoms are sold separately so you can find your ideal fit in every style. Please refer to the size guide below for sizing recommendations.
How to find your size
All Bikini Break pieces run true to size in XS, S, M, L, XL. If you are between two sizes, we recommend sizing up for tops (especially balconette and underwire styles) and sizing down for bottoms as our fabrics have stretch.
Size chart
| Size | Bust (in) | Underbust (in) | Waist (in) | Hips (in) |
|---|---|---|---|---|
| XS | 30 to 32 | 23 to 26 | 24 to 25 | 33 to 34 |
| S | 32 to 34 | 26 to 29 | 26 to 27 | 35 to 36 |
| M | 34 to 36 | 30 to 33 | 28 to 29 | 37 to 38 |
| L | 36 to 38 | 34 to 37 | 30 to 31 | 39 to 40 |
| XL | 38 to 40 | 38 to 41 | 32 to 34 | 41 to 43 |
How to measure
Bust: Measure around the fullest part of your bust. Keep the tape level all the way around your body, parallel to the floor.
Underbust: Wrap the tape around your ribcage just under your bust, snug but not tight.
Waist: Find the smallest part of your torso, usually just above your belly button. Measure all the way around.
Hips: Stand with your feet together and measure the fullest part of your hips.
If two pieces of a set fit differently (very common!), we always recommend mixing sizes. Our tops and bottoms are sold separately so you can find your best fit.
Fit notes by style
Underwire and balconette tops Tan Session, Weekend Spot give the most lift and structure. Size up if you are between sizes or want extra comfort.
Halter tops Wave Break, Beach Date, Sweet Escape tie at the neck and back for a fully adjustable fit.
Tankini tops Treat Time, Beach Date have a longer length that hits at the hip. Pair with any bottom for more coverage.
Cheeky cut bottoms (most of our bottoms) sit higher on the leg and give moderate coverage. The waistband sits at the natural hip.
Side tie bottoms Sweet Escape, Checked Out, Beach Date are fully adjustable. Loosen the ties to size up, tighten to size down. The kindest fit if you are between sizes.
