Buying Guide

Size and fit matter

Check brand sizing charts and age ranges—many items list 3–24 months—since rompers and dress styles can run differently across manufacturers

Fabric and comfort

Prioritize soft, breathable materials like cotton blends and flannel to reduce irritation for babies during extended wear

Ease of changing

Look for snap closures or zipper access at the crotch and chest to make diaper changes and dressing simpler

Safety and small parts

Avoid costumes with loose buttons, beads, or long ties; ensure decorations are securely sewn to reduce choking and entanglement risks

Layering for weather

Select costumes that accommodate layering—leggings or a bodysuit underneath—so the outfit works from indoor parties to outdoor trick-or-treating
