A full costume can make a character feel more real, but it's not required to have a great murder mystery party. A single well-chosen accessory often does more work than an elaborate outfit, and it keeps the barrier to entry low for guests who don't want to shop for a costume.
The One-Accessory Rule
Instead of asking guests for a full costume, ask each person to bring or wear one item tied to their character — a hat, a scarf, a pair of glasses, an old-fashioned brooch. It's enough of a visual cue to help everyone remember who's playing who, without turning the party into a costume contest.
Ideas by Theme
- Vintage/noir — a fedora, suspenders, a string of pearls, or a cigarette holder prop
- Gothic or horror — dark colors, a black shawl or cape, an old brooch or locket
- High society/formal — statement jewelry, gloves, a bow tie, or a pocket square
- Fantasy or medieval — a simple cloak, a costume crown, or a prop weapon
Props That Do More Than Costumes
A prop tied directly to the plot — a fake letter, an old photograph, a locket with a "clue" inside — often adds more to the story than a costume does, since it gives guests something physical to discover and discuss mid-game.
When to Go All Out
If your group loves dressing up, there's nothing wrong with full costumes — just make sure everyone has a similar level of effort in mind ahead of time so no one shows up underdressed next to a guest in a full period outfit. Setting expectations in the invite usually solves this.
