Most listings specify a 60% cotton / 40% polyester blend; one listing only notes "100% fabric."
Most coveralls use a front zipper (often described as zip-up front with a ring-snap zipper chin guard). One jumpsuit option lists Velcro closures for easier dressing.
Common features include ribbed sleeve and ankle cuffs, a comfortable hood lining, and soft, durable materials to support fit and all-day comfort.
These are mainly labeled as costume bodysuits or costume jumpsuits. Themes listed include TV/Movie, and one item adds Cartoon/Video Game.
Many feature screen-print artwork and dimensional/3D ears on the hood. One jumpsuit also lists a detachable headpiece with a character face, felt ears, and a removable tail.
