Kids' costumes use standard children's sizing with age/size notes such as “Boys' size Large (10/12)” or labels like “6 Years and Up” to guide fit.
Adult sets typically include a padded jumpsuit plus accessories such as an eye mask and gloves; some listings also list briefs and boot-cover–style details as part of the set.
The muscular shape is achieved with fiberfill padding sewn into the chest, shoulders, and thighs to create a stronger, padded silhouette.
Adult bodysuits typically use a back zipper for entry, while some kids' jumpsuits are pull-on or include a hook-and-loop (Velcro) closure for easier dressing.
Masks are foam eye masks with an elastic strap that fits around the back of the head. Gloves are forearm-length and designed to slide on for a snug fit.
Pant legs typically end in elastic stirrups and include a black band that mimics boot covers; the stirrups and band help keep the pant legs secured and create the boot look.
The black fabric is described as having a shiny, faux-leather coating.
