Greatest Hallowem costume? Boxer Mayweather dresses as a member of Run DMC

Floyd Mayweather decided to dress up for Halloween in a far less conventional outfit as the undefeated boxer decided to wear a Run DMC costume.

While most celebrities were getting into the Halloween festive spirit by wearing scary masks and costumes, Mayweather decided to be different by mimicking the traditional outfits worn by members of the American hip hop group.

Mayweather attended what was described as the 'biggest Halloween party of the year' with two members of his management team.
