The good girl gone bad has always brought the sexy for all of her record busting sold our tours. Who could forget her crazy Lisa-Frank mosaic two-piece? Or her pants-free basketball jersey look. Or her megalomania Mouseketeer steez from the summer of 2010? Riri's has one of the most killer wardrobes in town, and we can't wait to see what she'll rock tonight for the Diamonds kickoff show in Buffalo. Will she give nutty fashionistas Lady Gaga, Nicki Minaj or Katy Perry a run for their money? We're kind of betting on it. We can't wait to see! To tide us over in the meantime, we're counting down her 20 sexiest concert costumes of all time. Enjoy!
