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.
Good times.
