How to put it together

1
Put on a pair of dark jeans or black pants that you do not mind potentially getting stained.
2
Put on the white 'Problem Solved' graphic t-shirt.
3
If your shirt is not pre-splattered, lay it flat outdoors and flick liquid fake blood or red paint across the front using a paint brush.
4
Allow the fake blood on the shirt to dry completely before wearing it to prevent smearing.
5
Apply a few small smudges of fake blood to your hands, arms, or face for an extra disheveled look.
6
Carry your plastic prop weapon to complete the dark, comedic horror aesthetic.

Makeup & hair

Keep your hair messy and unkempt. You can add a few smudges of fake blood or dark eyeshadow around your cheeks and forehead to look slightly chaotic.
