Collection: Teen Costumes

Teen costumes cover the sizes that sit between kids and adults, so the fit is right for older kids and younger teenagers without swamping them. Most teens start with one bold statement piece, a graphic hoodie, a themed dress or a character jacket, then build the rest of the look around it with items they might already own. Pick a costume your teen actually likes rather than a generic size-down adult option, or check our girl Halloween costumes and boy Halloween costumes for younger sizes.

Teen costumes that fit right

Standard kids sizing often stops too small and adult sizing starts too big, so a proper teen size range makes a real difference to comfort and confidence on the night. Sizing by height and chest rather than age alone helps you land on the right fit first time. Our kids Halloween costumes collection covers the younger sizes if your teen is smaller framed.

Group and friend group costumes

Teens often want to coordinate with a group of friends rather than wear a single character alone, whether that is a themed decade look or matching horror characters. Agree the theme early so everyone can find pieces in the same size range. Browse group fancy dress for ideas that work across a bigger friend group.

Pop culture and trending looks

Teens tend to follow whatever is trending that year, from a specific film character to a viral social media look, so stock changes fast around Halloween. A single accessory or graphic tee can carry a recognisable reference without needing a full costume. Check famous people costumes for current celebrity-inspired options.
