Size Guide

Think an exaggerated ruffle will make your bust look bigger? Think again.

Ava is the most feminine, pretty and summery bikini top for busty women. Unlike other ruffled bikini tops, we've curved the neckline and tapered our ruffle so it works with the curve of your bust. Designed by a busty woman, for busty women.


  • Fully underwired
  • Plunge style
  • Adjustable straps
  • Adjustable back 

Fitters notes

If you need extra support in the top of your bust, then we suggest you try our Emelie Bikini Top.


Recently been professionally fitted? Then order your usual bra size. Otherwise complete our online e-Fitting form as we'll get back to you with your size in our swimwear.


Fact: Sizes vary across different brands.

We deliberately do not supply the measurements for our tops because if a customer makes a mistake when measuring herself, this can lead to the wrong size top being purchased. Instead we offer an e-Fitting service. 

Check your size in our products before purchasing and save yourself the possible hassle of exchanging it for another size. There is nothing more satisfying than nailing your size first time!
