How to put it together
- 1
Put on the white skin-tight jumpsuit, ensuring the slits on the forearms and calves sit correctly.
- 2
Style the two-tone wig, brushing the bangs straight down and letting the long yellow and orange sides frame your face.
- 3
Fasten the wide black and red belt around your waist, positioning the large gold buckle front and center.
- 4
Clasp the gold ankh necklace around your neck so the pendant rests flat against your collarbone.
- 5
Secure the pumpkin ball and chain prop around your left ankle using a soft strap under the jumpsuit cuff.
- 6
Position the white pumpkin mask on the side of your head, securing it with bobby pins or its elastic strap.
- 7
Complete the look with red fingerless gloves and matching white boots with red trim.
Makeup & hair
Keep makeup clean with a pale complexion, neutral lips, and subtle red eyeliner. The hair is the focal point: a long, straight wig split vertically down the middle with bright yellow on the left and vibrant orange-red on the right, featuring neat, blunt bangs.

Tips
- Use double-sided fashion tape along the arm and leg slits of the jumpsuit to keep them from shifting while you move.
- Keep the ankle ball-and-chain prop lightweight by using hollow plastic or foam so it doesn't drag or trip you up.

- Practice the famous 'Jack-O pose' (crouching low with hips high) for photos, but stretch beforehand to avoid pulling a muscle.
