About this costume
Every party needs a mystery, and this Halloween costume idea makes you the one solving it. A trench coat, a fedora, and a magnifying glass turn the classic detective costume into an easy, recognizable Halloween costume for adults who want noir style without a single drop of fake blood.
DIY this look
The detective costume might be the single easiest Halloween costume idea to assemble - trench coat, hat, done.
- Wear any trench coat or long dark coat over a plain shirt and tie.
- Tilt the felt fedora low over one eye.
- Tuck the notebook in one pocket and keep the magnifier in hand.
- Add the candy prop for photos, mystery-novel optional.
