Buying Guide

Look for ruched belly panels

Ruching across the belly lets the suit expand with your bump while camouflaging lines and maintaining a flattering silhouette

Choose adjustable straps

Adjustable or convertible straps provide better shoulder support as body proportions change and allow you to customize fit

Prefer removable padding for versatility

Removable padding lets you add shape or remove inserts for breastfeeding, comfort, or easier drying

Check fabric blend and stretch

Look for nylon/spandex or polyester/spandex blends with good recovery to balance comfort, chlorine resistance, and fit retention

Consider front-cross or wrap designs

Front-cross and wrap styles offer adjustable coverage and easy accommodation for a growing belly without sacrificing support
