Kids Halloween costumes need to fit over warm clothes, stay visible in the dark, and survive a couple of hours of walking. Most children's costumes cost $20 to $50. Everything on this page is a live retailer listing with a current price and a direct link to buy.
Costumes built for actual kids: easy to wear over a jacket, easy to move in, and easy to order in time.
Trick-or-treating is an outdoor walk in the dark, so the practical costume usually wins. Look for a design that works with a coat underneath, doesn't drag on the ground, and doesn't rely on a full-face mask that blocks peripheral vision — a hood or face paint is safer. Reflective trim or a light-up element is a genuine safety feature, not a gimmick.
Children's costume sizing is by age band, and those bands run small. Size up one band if your child is on the older end of theirs or if it will be cold. Check that trousers and capes sit above the ankle, and that any headpiece has an elastic that can be adjusted rather than a fixed circumference.
Most kids' costumes sit between $20 and $50, with licensed characters at the top of that range and simple animal or classic-monster styles at the bottom. Accessory sets that build on clothes you already own can come in under $15.
Kids' sizes sell out earliest, especially popular character costumes in the 4-6 and 7-8 bands. Ordering in the first half of October gives you room to exchange a size. Standard shipping is three to five business days from most retailers.
