Katy Perry's doing her best to compete with Milan Fashion Week.
The singer performed at the Assago Forum in Milan and went outfit crazy, changing into a number of different ensembles during her performance, part of her California Dreams World Tour.
She donned a blue wig and tiered cupcake ensemble, and also sported several different candy-themed dresses, including a white and red look, a caramel and pink dress, a toffee yellow frock, a mint green ensemble, and a blue dress with printed peppermint lollipops.
Perry also changed into a sequinned tutu dress and a bedazzled leotard, which she wore while singing alongside a purple cat (the mascot for her fragrance, Purr).
Perry donned a black wig as she played the flute in a citrus-y-inspired dress, and went from candy girl to catwoman in a skintight leather catsuit with slits and cat's ears.
Meow. We mean, Wow.
