Costume sizes vary between brands, so always check the size chart on the retailer’s product page before you buy. Here are a few tips to help you get it right first time.
Adult costumes
- Measure your chest (around the fullest part), waist and inside leg, and compare them with the brand’s chart.
- If you’re between sizes, choose the larger one – most costumes are designed to go over your clothes.
- One-size costumes usually fit UK sizes 10–16 for women and medium–large for men, but check the listing.
- Onesies and jumpsuits are measured by height as well as chest, so check both.
Kids’ costumes
- Kids’ costumes are normally sized by age, but height is the better guide – check the height range on the listing.
- If your child is tall for their age, go up a size. A slightly big costume is easier to wear than a tight one.
- Leave room for a vest or long-sleeve top underneath for chilly trick-or-treating or school days.
Wigs and hats
Most fancy dress wigs and hats are one size with an adjustable or stretchy fit. Tuck long hair under a wig cap for the best result.
Still not sure?
Reviews on the retailer’s page are a great guide to fit – other buyers often say whether a costume comes up big or small.
