How to put it together
- 1
Put on comfortable, lightweight base clothes like a t-shirt and shorts underneath the jumpsuit.
- 2
Step into the yellow hooded coveralls and pull them up to your shoulders, but leave the zipper open for now.
- 3
Put on your black boots and tuck the elastic cuffs of the jumpsuit pants securely inside the boots.
- 4
Pull the hood of the jumpsuit over your head and zip the front of the coveralls all the way up to your chin.
- 5
Position the respirator mask over your nose and mouth, securing the straps behind your head and over the hood.
- 6
Slip on the clear safety goggles, placing the strap over the hood to keep everything sealed.
- 7
Pull on the blue nitrile gloves, ensuring they overlap and cover the elastic cuffs of the jumpsuit sleeves.
Makeup & hair
Keep hair tied back flat against your head or in a low bun so the hood fits comfortably. No makeup is needed since the lower face is covered by the respirator mask and the eyes are behind goggles.

Tips
- These suits are made of non-breathable materials and can get very warm; wear light, moisture-wicking clothes underneath.
- If you plan on eating or drinking at a party, choose a respirator mask that can easily hang around your neck when not in use.
- To make the suit look weathered or post-apocalyptic, smudge charcoal powder or dark eyeshadow onto the knees, elbows, and seams.
- For fun photos, carry a roll of yellow 'CAUTION' or 'BIOHAZARD' barricade tape to wrap around your group.
Hazmat Suit costume FAQ
- What do you wear under a hazmat suit costume?
- Wear lightweight, breathable clothing like a cotton t-shirt and athletic shorts, as the synthetic material of the suit traps heat quickly.
- How do you make a cheap DIY hazmat suit?
- Buy a pair of cheap disposable yellow painter's coveralls, draw a black biohazard symbol on the chest with a marker, and wear yellow dishwashing gloves and safety glasses.
- Is a real hazmat suit safe to wear for Halloween?
- Real industrial hazmat suits are safe but extremely hot and uncomfortable. It is highly recommended to use lightweight costume-grade coveralls or disposable painter's suits instead.
Did you know? While real hazmat suits come in various colors depending on the chemical threat level, pop culture almost always depicts them in bright yellow or orange for maximum visual impact on screen.
