How to put it together
- 1
Put on your base layer of solid black or red clothing for a clean, uniform look under the tunic.
- 2
Slip the foam Diet Coke can tunic over your head, adjusting the shoulder straps or side ties for a comfortable fit.
- 3
Construct the soda tab headband by wrapping a cardboard tab shape in foil and securing it to a plain headband.
- 4
Put on your red or silver shoes to tie the color palette together.
- 5
Smooth out any wrinkles in the foam tunic so the logo is clearly visible from the front.
Makeup & hair
Keep makeup simple with a bold red lip to match the classic Coca-Cola red. Style hair in a sleek ponytail or bun to keep it out of the way of the headband and tunic.

- What should I wear under a foam soda can costume?
- Solid black or red leggings and a long-sleeve shirt work best to keep the focus on the silver can design.
