WELCOME TO BAIIA
Or pay in 4 interest-free instalments of $32.25 with
Grounded by nature, shaped by the unknown. The Reef Reversible Bikini Bottoms bring together Corallo Red and Husk Brown in a considered colour-block inspired by the hidden world beneath the water. Bold yet earthy. Reversible by design, each side reveals a different expression, balancing statement colour with natural depth. Thoughtfully cut to flatter your shape with a more relaxed feel. Reef offers a secure, comfortable, supportive fit with a smoothing, held-in feel, made for discovering what lies beyond the surface.
Pair with the Reef Classic Bikini Top to create a versatile swimwear set with multiple ways to wear, where unexpected beauty meets natural grounding.
Our signature Italian swimwear fabric is made from 70% recycled nylon and 14% spandex, using regenerated fibres from pre- and post-consumer waste, including ocean waste. Luxuriously soft and more flexible than our signature recycled polyester fabric, this nylon blend offers a more relaxed fit while maintaining supportive hold for A to H cups. For a firmer, more sculpted fit, we recommend sizing down.

Height: 173cm
Julia (blonde hair) wears a Size US 2. Her measurements are:

HOW IT WORKS
Each Baiia swim piece is customisable with waist ties or style shifters so you can adjust your bust support and coverage, your way.
Double and triple-lined fabric do the work of shapewear, hugging your shape and smoothing as you move, without harsh lines, digging, or discomfort.
Our patented reversible design ensures both sides are fully wearable, so you're never just buying one suit - you're getting multiple looks in one.
