Never afraid of the depths, always drawn to more. The Siren Reversible Bikini Bottoms bring together a delicate floral and retro-inspired stripe in Corallo Red, softened by hints of pink. Reversible by design, each side offers a different expression of Siren’s untamed femininity. Thoughtfully cut to sculpt, shape and flatter your natural shape, they deliver a secure, supportive fit with a smoothing feel, made for a woman who carries her softness through every storm.
Pair with the Siren Classic Bikini Top or Siren One-Piece Wrap Top to create a versatile reversible bikini set, with multiple ways to wear and a little more freedom to follow wherever the tide takes you.
Our signature Italian swimwear fabric is made from 78% recycled polyester and 22% spandex, using regenerated fibres from pre- and post-consumer waste. Luxuriously soft yet firm, this high-performance fabric offers a structured, shape-controlling fit with supportive hold for A to H cups. Due to its technical construction, expect a firmer feel than conventional swimwear.

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.
