Bettylicious sells the high quality US swimwear 1 size difference than the UK.  All swimwear will have US labels on and stickers with UK equivalent sizing on when dispatched.  Please note this when it arrives.  Most of the swimwear is true to UK sizing apart from some swimsuits that has a limited stretch  eg, metallic and polka dot.  Betty’s advice is to size up on these.


We suggest you start with your hip measurements. The halter tops on the Classic Sheath and the Two-Piece Classic can be adjusted a bit, and the tummy control will often fit to the waist — but hips are where we hear the suits can be a little snug

If in doubt, please size up — our suits can run slightly small when compared to dress sizes.

Long Torsos: We don’t have a Long Torso option with our suits. The stretch in the Classic Sheath is so versatile, we’ve been told by customers that simply sizing up will accommodate the length of their torso. Of course, the Two-Piece is also a good option for long torsos.

These measurements are true for our suits:
