Britney Spears kicks off another tour tonight in Sacramento, CA -- and, if her past proves anything, there's going to be a lot of crazy costume changes!
We'll be posting photos from her new concert with Nicki Minaj as soon as they start coming in later this evening, but to hold you over until then, check out some of her wildest on stage looks over the years.
Whether it was her innocent-yet-sexy start up outfits to the racy S&M gear she wore at the Billboard Music Awards last month, see how her stage style has changed since she first hit the scene!
