Adult Costumes

Halloween, themed bachelorette parties, masquerade nights, costume galas — adult costumes work best when they're specific enough to be recognisable without being so elaborate that comfort is sacrificed. The best adult costumes balance a clear character or concept with the ability to wear it for four to five hours through a party. We carry a range of adult costume options from full character kits to mix-and-match pieces that let you build your own look.

Sizing is one of the most common costume frustrations. Adult costume sizing in party supply products tends to run small — a size L is often closer to a regular M. We always recommend checking the specific size chart for each costume rather than going by the label. When in doubt, size up: a looser costume is far more comfortable than one that's too tight, and most pieces can be adjusted at the waist with a belt or safety pin.
