Frequently Asked Questions

What if my measurements fall between two sizes?

Always go with the larger size. Costumes that are too tight are uncomfortable and can tear, especially during active wear at parties or events. A slightly loose costume can be adjusted with safety pins, a belt, or temporary alterations. Most rental companies also offer minor adjustments at pickup.

Are costume sizes the same as regular clothing sizes?

Not always. Costume sizing tends to run smaller than everyday clothing brands. A person who wears a medium in regular clothes may need a large in many costume brands. Always go by actual measurements rather than your usual clothing size when ordering a rental costume.

How should I size costumes for kids who are growing quickly?

For children, size based on height first, then chest. Kids' growth spurts make height the most variable measurement. A costume that is slightly long can be cuffed or pinned, but one that is too short cannot be fixed. For events a few weeks away, consider sizing up one level.
