How to put it together
- 1
Put on the dark gray school trousers and the plain white crewneck t-shirt.
- 2
Put on the Hyosan High School jacket, leaving it fully unzipped and hanging open.
- 3
Apply fake blood to the front of the white t-shirt and the collar/lapels of the jacket to mimic his violent encounters.
- 4
Style your hair to look messy, sweaty, and slightly disheveled.
- 5
Apply zombie makeup, focusing on a pale complexion, dark under-eye circles, and blood dripping from the mouth or nose.
- 6
Put on the scuffed white sneakers to complete the high school student look.
Makeup & hair
Style your hair to look messy, damp, and pushed back. Use pale foundation or face powder for a sickly, half-dead complexion, then add dark purple and brown eyeshadow under the eyes to create deep hollows. Add a streak of fake blood dripping from one eye, the nose, or the corner of the mouth.
