DETAILS THAT MATTER This fun costume is designed by our talented Pottery Barn Kids team who personally make the first sample and plan every special detail. Our costume is finished in garment-quality stitching and construction so it can be handed down to siblings and worn for years to come. Made of 100% polyester velour and reverses to polyester satin. Costume glows in the dark. Glow-in-the-dark material needs to “charge” under bright light for approximately half an hour to glow properly. Glow lasts for approximately three to four hours. The glow effect will become weaker over time with constant use. Costume is yarn-dyed – fibers are treated individually with environmentally safe dyes before weaving to offer vibrant, lasting colors. Undergarments and leggings are not included.
