Bikini Top Size Chart

As for our fabulous bikini tops we have four cuts to choose from:

Our surf bralette and fitness bikini tops are a dream for any avid sustainable surfer or yoga bunny looking for a bikini top that stays in place and also doubles as a sports bra. We also recommend these two cuts for ladies with a bigger bust as they are the most supportive. For the most support opt for our fitness bikini top. 

Then we have our triangle plunge bikini top and our fixed triangle bikini top; these both have the timeless triangle design but are very different. The Triangle Plunge design is clasp free, with a middle strap across the back to stop slipping straps not to mention some more support. 

Whilst the fixed triangle bikini tops has a more delicate unique back design held together with a rose gold clasp with adjustable straps. We suggest this top to our petite ladies as the fixed triangle bikini tops run slightly smaller.
