How to put it together
- 1
Choose your persona, such as a medical doctor, a research chemist, or a wild mad scientist.
- 2
Iron or steam the lab coat to remove packaging creases for a professional look, or leave it wrinkled for a chaotic vibe.
- 3
Put on your base layer, such as blue medical scrubs or a smart button-down shirt with trousers.
- 4
Slip on the lab coat, leaving it open to show your under-clothing.
- 5
Clip your personalized ID badge to the left breast pocket of the coat.
- 6
Drape the stethoscope around your neck for a doctor look, or slide the safety goggles onto your head for a scientist look.
Makeup & hair
Keep hair neat and parted for a professional doctor. For a mad scientist, tease your hair wild with hairspray and use black eyeshadow to smudge fake 'explosion' soot marks onto your cheeks.
