Most of the costume shirts and jumpsuit-style outfits are made from 100% polyester.
Sizing and suggested ages vary by listing: some options list toddler sizes (2–4 years), shirt listings cover roughly 2–9 years, and some sets are marked 5 years and up. Label types shown include Toddler, Boys Husky, and Kids.
Jumpsuit-style costumes commonly include a padded or printed jumpsuit and may add padded boot tops, a detachable cape, and a foam Batman headpiece. Shoes are generally not included.
Villain/deluxe sets commonly include a printed jumpsuit with an attached jacket and sometimes a wig. Makeup and shoes are generally not included.
The listings use theme labels such as TV/Movie and Action Superhero to describe the costume styles.
