Floyd Mayweather Rocks Versace Cape In Miami

Floyd Mayweather has one-up on Superman ... his cape is designer made.

The boxer was pre-gaming in Miami before hitting the clubs with his pal, Adrien Broner -- rocking a Versace robe with a matching blanket he used as a cape.

A short time later, they hopped in a TMT Jeep -- customized with TMT rims.

Inside the club, there was dancing, drinking and ladies.
