How to put it together
- 1
Put on the base yellow jumpsuit or the matching compression shirt and leggings.
- 2
Secure the inverted red and black lightning bolt emblem to the center of the chest if it is not already integrated.
- 3
Step into the yellow boots or pull the matching yellow boot covers over your shoes.
- 4
Put on the yellow and black gloves, ensuring they tuck neatly under the sleeves of the jumpsuit.
- 5
If using LED eye inserts, secure them inside the cowl according to the product instructions before putting the mask on.
- 6
Carefully pull on the yellow cowl mask, aligning the eyeholes and mouth opening comfortably.
Makeup & hair
Since the cowl covers the hair and upper face, focus on dark, smoky eyeshadow around the eyes to blend into the mask's eye cutouts, or wear red cosmetic contact lenses for a menacing look.

Reverse Flash costume FAQ
