Put on your neutral base layers, such as a solid black or matching blue long-sleeve shirt and pants.
- 2
Carefully slip the foam water bottle tunic over your head, aligning your arms with the side armholes.
- 3
Adjust the tunic so the printed brand label faces directly forward and sits flat against your chest.
- 4
Secure the bottle cap hat onto your head, using bobby pins if needed to keep it upright and centered.
- 5
Ensure you can walk and move your arms comfortably, adjusting the bottom hem of the tunic if necessary.
Makeup & hair
