Listings typically show sizes from 1X through 5X. Many titles indicate 1X–4X and descriptions explicitly list availability in 1X, 2X, 3X, 4X, and 5X.
Materials commonly listed include 100% polyester, polyester satin and crepe blends for some dresses, velvet ribbon trim, and twill (notably a 93% polyester / 7% cotton twill).
Common closures and adjustments include front or back zippers, zippered pockets and hems, hook-and-loop (Velcro) fasteners for belts and adjustable cuffs, and elastic or adjustable waist straps to tailor the fit.
Designs range from floor-length gowns with full or leg-of-mutton sleeves to shorter, above-knee dresses with cuffed short sleeves—so both long, dramatic silhouettes and shorter, casual styles are available.
Several costumes include functional proton-pack–style backpacks or canvas backpacks with zipper closures, adjustable (sometimes padded) shoulder straps, and attached foam wands or tubing for prop use.
