Buying Guide

Prioritize safe materials

Choose costumes made from breathable, flame-resistant fabrics and soft seams to reduce irritation on sensitive baby skin

Check sizing and fit

Look for romper styles or adjustable closures and follow manufacturer size charts to ensure room for diapering and layering

Prefer easy on/off designs

Rompers with snaps or full-length zippers simplify diaper changes and dressing up a squirmy baby

Mind hood and accessory safety

Ensure hoods are detachable or loose-fitting and that accessories are non-choking and securely attached

Balance novelty and practicality

Select costumes with playful details that won’t impede movement or overheating during parties and outdoor wear
