How to put it together

1
Choose your character: opt for Six's yellow raincoat look or Mono's paper bag and trench coat ensemble.
2
If playing Six, put on the oversized yellow raincoat and pull the large hood forward to partially shadow your face.
3
If playing Mono, cut two small, round eye holes into the brown paper bag, slip it over your head, and adjust for visibility.
4
For Mono, put on the dark grey trousers, roll the cuffs up to mid-calf, and wear the oversized olive or grey trench coat over them.
5
Go barefoot to match the game's authentic, vulnerable aesthetic, or wear flesh-colored socks/invisible flats for comfort.
6
Carry your character's signature prop: a brass lighter for Six, or a small toy flashlight or key for Mono.

Makeup & hair

For Six, style your hair in a short, dark bob with straight bangs that cover your eyes, or use a wig. For Mono, no hair or makeup is needed as the paper bag completely covers your head.

Tips

If you choose to go barefoot for photos, bring slip-on shoes or flesh-colored flats to wear while walking around outdoors or at a convention.
To make Mono's paper bag mask sturdier, line the inside with a thin cardboard band or a clean baseball cap with the brim removed.
Use a matte black mesh fabric glued inside Mono's eye holes to hide your eyes while still allowing you to see out.
