I made the Randy Savage costume from scratch. The hat and sunglasses are from a party store (with some help from red and yellow electrical tape). A black and white bandanna, the tie dye shirt is homemade by me. I took an ordinary red shirt and cut it up to give it affect, and used a black Sharpie and yellow tape to the OH YEAH! The pants are from a retro thrift store, and the World Heavyweight Championship belt is from a toy store.
I grew a beard, and taped my wrists and fingers for added effect. And of course.. bought a box of Slim Jims.
