Most options are polyester (several list 100% or 86% polyester). At least one dress uses a nylon/spandex blend for the yoke and sleeves (96% nylon, 4% spandex).
Sizing is listed as women's sizes (commonly S, M, L). The suggested age is typically labeled as “Adult” or explicitly “18 Years and Up.”
Some garments use a concealed back zipper for easy dressing. Accessories may use cords with a short chain and a small metal lobster‑claw clasp (e.g., on a plastic shell necklace).
At least one costume includes a light-up plastic shell that requires two CR2032 button batteries (demo batteries included). Other items explicitly list “Battery: No Battery Used.”
One costume specifies spot cleaning with a sponge and advises against machine washing, tumble drying, or ironing. Most other product details don’t specify care—check the individual item’s care instructions or label before cleaning.
Styles range from modern asymmetrical sleeves and mismatched stockings (bandage‑print sets) to pieces with attached draping or tie‑gauze strip headbands that create a wrapped look.
