7. Mike Tyson's Black Trunks/No Robe Combination

Debuted: 1985
Famed Appearance: Versus Michael Spinks for the heavyweight championship of the world

It's what Iron Mike Tyson chose not to wear during his Heavyweight Championship bout with Michael Spinks that is truly startling. Tyson emerged from the dressing room in the Trump Plaza in Atlantic City wearing his signature black trunks, but with no top. No towel. Nothing. He even chose to enter with nothing but ominous sounds of chains hitting concrete in lieu of traditional entrance music. Tyson looked like he was there to fight…and he did for 91 seconds before knocking Spinks out.
