A full piece swimsuit with underwire support is the ideal choice for women seeking comfort and shape for their bust.

It moves the bust away from the mid section so you can show of your waist and curves in all their wonderful glory. Consider an underwire one piece for your next perfectly fitting swimsuit.

Size guide

All of our swimsuits are true to size. This means you should follow your normal sizing.

The best guide is your underwear - so what you would wear in a bra and undies is the size you order from us in tops and bottoms. For example, in you wear an 18E bra, you should order a size 18 swimsuit top from us.

If you are looking for a one piece and are in between sizes, say an 18E bra and a 20 in underpants, we recommend choosing the larger of the two sizes - so a size 20 in this case.

If you have any issues with your new swimsuit, we do 30 day refunds for full priced items and exchanges for all items - so you can swap to a size or style that is more suitable for you!
