Before you buy a kids' costume

How do I pick the right costume size?

Costume sizing runs differently from everyday clothes, and listings often run small. Measure your child against the size chart on the Amazon listing before ordering, and consider sizing up if they're between sizes or will wear warm layers underneath on Halloween night.

Are these costumes safe for trick-or-treating?

Most kids' costumes are made of polyester — keep them away from open flames, and check the listing's safety warnings. Light-up or glow-in-the-dark designs add visibility on dark streets, which is a nice bonus. Skip loose accessories or long trailing pieces that could cause tripping.

How do I care for a kids' costume?

Follow the tag instructions on each listing: many polyester costumes are spot-clean or hand-wash only to protect prints, lights, and glow features. Let costumes air-dry flat rather than tumble drying, and store them folded or hanging so they're ready to wear again next year.
