Sizes vary by item. Many costumes list suggested ages such as 5–12 years or “5 years and up.” Graphic t-shirts commonly cover ages 2–14 (sizes 2T through YXL). Some costumes show explicit size ranges labeled Small (5–6 years) through X-Large (11–12 years). Always check the specific item size chart before buying.
Common materials include polyester (many costume pieces listed as 100% polyester), polyester blends with spandex for stretch (for example 95% polyester/5% spandex), and knit tees made from cotton/poly blends (e.g., 60% cotton/40% polyester). One boys' costume also lists polyester interlock knit, gabardine, and satin for specific pieces.
Care varies by item. Graphic t-shirts typically advise machine wash cold, inside out, with like colors and tumble dry low (or hang to dry). Many costume pieces recommend gentler cleaning—sponge clean only—and warn against bleaching, tumble drying, or ironing. Follow the specific item’s care label for best results.
Many outfits use stretch and flexible fabrics to support active play. Examples include stretchy leggings and polyester/spandex knit blends described as soft and flexible—these give range of motion and comfort so kids can dance easily.
Most costume sets require no batteries. The electronic DJ mixer toy does need batteries—specifically 4 AA batteries (listings indicate 4 AA alkaline in at least one case). Check the product page for the exact power requirements.
Listings advise shoppers to check each product’s size chart. The graphic tee is described as fitting true to size and covers ages 2–14 in its size range; some costume descriptions explicitly tell buyers to review the size chart to ensure a comfortable, flattering fit.
