How to Dress Like One-Punch Man

Bald Head:

Saitama is completely bald to the point of always having a shiny spot on his head. You can use a bald cap to achieve this look or go the dedicated route and bic your head. Make sure to slap on some grease to get that shiny look.


Saitama wears a yellow bodysuit. You can choose to wear a yellow waterproof coat and pants, you just have to put the coat inside your pants to create a suit that fits your body. Another way is to wear a yellow jumpsuit.


Use a black belt with a gold-colored buckle. A web style cloth belt will work well for this part of the costume. You can easily find one on Amazon or other stores.


Like many superheroes, One-Punch Man wears long red gloves. You can find these at most costume stores or on sites like Amazon.


To make the cape you can use the white bedsheet. It is better to use a heavier material to make sure it flows well while in action. You can also buy white capes and cloaks at costume shops.
