Katy Perry's post-performance appearance at the MTV Movie Awards was quite a sexy one! Yes, the lady stepped on the red-carpet in a Hervé Léger by Max Azria Fall 2010 dress, which was looking ravishing on her. The only problem were her hair, I am still wondering why she shaded them to blue? Well, the hair were disgusting, they were making her look like a porn star. Another cool thing was her shoes, she wore Rock & Republic Lotus platform pumps, which were matching perfectly with her attire. If I leave her horribly colored hair aside, then the look was quite a chic one. Have a look at the pictures below.
