not sure if the latex fabric actually works. maybe a cloth kind of texture works better? what do you guys think?
edit:
(this is from the fandom wiki)
Vault jumpsuits are the regulation clothing carried by the vault dwellers of Vault-Tec vaults. They are made of leather, blue with a yellow zipper and the number of the vault is on the back of the suit and on the outside of the collar.
so i guess its leather.
