How to size a kids costume

Sizes are shown three ways in the titles: age bands like 4 - 6 Years or 10 - 12 Years, letter sizes like M, L, XL and XXL, and height, such as the Boys Army Boy Deluxe Costume - 140cm. Measure your child's height and compare it with the clothes they wear now; if they sit between two sizes, go up, because costumes are pulled on over a T-shirt and shorts. Try it on a few days before the event so there is time to adjust. For a witch or wizard, finish with a hat and broom from our witches and wizards range, and for any face paint, do a patch test first and follow the packet directions.
