Dressed in head-to-toe Prada, the star made a return to the candy-coloured outfits, aside from her hair of course which looked to be a brighter shade of blue than ever before. (No wonder she's wearing sunglasses...)
While there's nothing wrong the versatile ponytail, this particular style doesn't exactly look comfortable to us. Yes, at this kind of height, she could swish her hair around in the style of a cheerleader but we can't imagine that even Perry could get away with that at a fashion show.
