Murder mystery party costume ideas

Easy costume ideas for 24 murder mystery characters, from a plague doctor to a 1920s bootlegger, plus how to dress up on almost no budget.

The one-item rule

Tell your guests that one strong item is a full costume. A mask, a hat, a prop or a string of pearls is enough to get into character. Guests who want to go all out will, and nobody else feels pressured to spend money.

Costume ideas under $10

  • A masquerade mask: fits any gothic or Halloween character.
  • A hat: fedora, flat cap, top hat, cloche or chef's cap instantly signals a role.
  • A prop: a doctor's bag, a notebook, a deck of cards, a bar towel or a toy microphone.
  • An accessory: pearls, suspenders, a bow tie, gloves or a feather boa.
