Buying Guide

Fit and adjustable support

Choose suits with adjustable straps or front-cross designs to customize support as your body changes during pregnancy

Ruching and stretch fabric

Look for side ruching and high-stretch materials that provide a forgiving fit and flatter a growing bump without restricting movement

Removable padding and modest coverage

Removable padding lets you adjust shaping and comfort, while full-coverage cuts offer secure support for active swimming

Chlorine and UV resistance

Prioritize swim fabrics rated for chlorine and UV resistance to retain shape and color if you swim frequently or in sun-exposed pools

Sizing and return flexibility

Pick brands with clear size charts and flexible return options so you can try different sizes as your body changes through pregnancy
