Katy Perry Looks Sophisticated & Sexy On The 'Tonight Show'

The singer who is known for her risque style and quirky outfits stepped out in a totally toned down ensemble — and she looked absolutely fabulous!

Katy Perry made a guest appearance on The Tonight Show with Jay Leno on Jun. 21 to promote her new 3D documentary-concert movie Part of Me, and she shied away from her usual style. Instead, the beauty opted for a Roland Mouret Spring 2012 navy dress. The dress was detailed with red tulips and had ruffles cascading down the side — while it was definitely more sophisticated, I love how it had Katy’s signature flair!

She paired the look with red platform peep-toes and waved hair. Katy looked absolutely gorgeous and we are really loving this side of her. Do you like this refreshing change on the star?
