Sizing Guide

🔥 General sizing tip 1: For all swimwear, a snug fit on land is a good indication that it is going to stay on in the water. This is because swimwear fabric stretches and becomes heavier when wet. So if it fits just nice on land = loose in water. Fits snug on land = it’ll be okay to surf or swim in without you worrying about the swimsuit falling or slipping off.


🔥 General sizing tip 2: If you are purchasing with the intent to surf or do other sports & NEED it to stay on, choose according to size chart. Otherwise, you may choose 1 size up for a more relaxed fit to lounge or lightly swim in.


🔥 Sizing tip for ONE-PIECE SWIMSUITS: If your top is size S & bottom is size M, you may choose either S or M depending on what you’ll mainly use the suit for. For better hold = choose size S. For more relaxed fit = choose size M.

Best surfproof bikini I own!

I’ve been in the search for the ideal surf-kini that matches my body type and that could actually stay on without me constantly adjusting it while in the water and lemme just say that haikini’s thalassa set has been a GAME CHANGER! I’m honestly so happy with it and I definitely recommend, especially for big-chested girlies hehe.

Haikini Thalassa - Sports Classic Reversible Bikini Top With Fixed Padding Review

super cute

Received so many compliments on this top! I love the strappy detail behind and that it’s reversible – paired with white pants it’s perfect for lounging! I’m between sizes but I chose to stick to my usual sizing instead of sizing down. Feels secure and flattering for the itty bitty ***** club iykyk
