5. Tough Mudder
If you really want to go all out, this fitness-themed costume is for you. All you need for this is a t-shirt and shorts (tall socks and Under Armour optional). Just make sure the clothing you choose is stuff you don’t mind ruining. No need to go outside and get dirty – just cover yourself from head-to-toe with this chocolaty recipe for fake mud instead.
