Buying Guide

Prioritize fabric and comfort

Look for soft, breathable materials like cotton, fleece, or flannel and minimal scratchy trims to keep babies comfortable during wear

Check size and fit guidance

Choose costumes with clear age/weight sizing and adjustable features—like elastic waists or snaps—to avoid tight or restrictive fits

Evaluate safety features

Avoid long trailing pieces and loose embellishments; prefer costumes with secure closures and flame-resistant fabrics when possible

Consider ease of diaper changes

Select rompers or sets with snap crotch closures or two-piece outfits that make diaper changes quick and simple

Think about washability

Opt for machine-washable costumes or easy-care fabrics to simplify cleanup after Halloween or playdates
