Costumes
Costumes are allowed in carry-on and checked bags, but any prop weapon, blade, or toy gun follows its own item's rule.

Carry-on details
Allowed. A costume itself, as clothing or fabric, has no restriction. The catch is props — a prop sword, knife, or gun, even a clearly fake one, is generally evaluated the same as the real item it resembles, and realistic replicas are more likely to be flagged than obviously toy-like ones.
Checked-bag details
Allowed. The costume itself has no restriction in checked baggage; the same prop-weapon caveat applies.
Special instructions
If your costume includes a prop weapon, pack it in checked baggage to avoid any question at the checkpoint, and avoid highly realistic-looking replicas of real weapons.
FAQ
- Can I bring a costume prop sword in carry-on?
- It's risky — prop weapons, even toy ones, can be evaluated similarly to the real item, especially if they look realistic. Pack costume props in checked baggage instead.
