Buying Guide

Choose adjustable or ruched tops

Ruching and adjustable straps expand with your bump and provide a flattering fit through multiple trimesters

Look for two-piece sets for versatility

Two-piece tankinis separate top and bottom sizing, making it easier to mix sizes and reuse pieces after pregnancy

Check fabric for stretch and recovery

Blends with spandex/ELASTANE offer stretch for comfort and recovery so the suit maintains shape across wear

Prioritize supportive bust features

Built-in shelf bras, thicker straps or soft cups add needed support without underwire during pregnancy
