How to Style the Backrooms Explorer Halloween Costume

The yellow suit gets noticed first, and it should look worn, not shiny and new. A brand-new suit reads like a store costume. With the mask on, nobody can see your face or hear you in a loud room, so people just walk past. Without the mask, you are a person in a yellow jumpsuit.

In the film, a furniture store owner and his therapist find the Backrooms through the store basement, then walk into endless empty rooms with something hunting them. Play your explorer the same way. Stop at every corner and listen before you turn it.

The mask fogs up

A full-face mask holds your breath and fogs the lens within minutes in a warm room. Wipe the inside with a dry cloth before you leave. Plan to pull it up on your head when you eat or drink.

Order the suit first

The suit is the item with the longest shipping time, so buy it before the small things. A suit that arrives on October 30 leaves no time to fix the size. Try it on the day it arrives.

Backrooms Explorer Group Halloween Costume Ideas

Duo Idea

Backrooms Explorer & the Entity

Strong if the second person puts real work into the monster. The film keeps its entity unseen, so the monster has to be a look you pick and then explain. The explorer is the easy half of this pair.

Group Idea: Async Team

Backrooms Explorer, Naren Warne & Phil

Might work, but only with people who saw the film. Naren is an Async explorer and Phil is an Async scientist, so the group reads as one research team once someone says so. In a crowd that has not seen it, you are three people in work clothes.

Duo Idea: The Film Leads

Clark & Dr. Mary Kline

Strong if both people know the film. Clark and his therapist are the two people who walk in first. This one does not include the explorer, so it works best as a second costume for a friend.

Backrooms Explorer Halloween Costume DIY Tips

Building the Look

Buy the suit and the mask. The rest you can often find at home.

Suit: buy it. A painted raincoat does not read right.
Mask: buy it, or wear any dark full-face mask you already own.
Boots: check your closet for black rain boots.
Tape: any black duct tape works if you do not want to buy gaffer tape.
Case: skip it unless you need somewhere to put your phone.
Flashlight: you may already have one.

Playing the Explorer at the Party

Be slow and quiet. An explorer who stops and listens is more fun than one who talks.

Point the flashlight at the floor, not at people’s faces.
Walk slowly and stop at doorways.
Keep the mask off while you eat or drink, and put it back on after.

No. The listed mask is a prop and is sold as non-protective. Do not wear it around real fumes or dust.

Can I wear this costume without the mask?

Is the hazmat suit hot to wear?

Expect it to run hot, so wear a thin shirt and shorts under it. Unzip it when you step outside.
