1) Katy in Zac Posen:
2) Katy in The Blonds:
Katy wore this Marchesa creation at the 2010 VMA's and she looked gorgeous, as usual. I'm a little obsessed with Marchesa dresses at the minute and I can never fault them, this dress is fun, sexy and pretty unique, like Katy herself. Those colourful streaks in her hair make the look even more fun, kudos to Katy!
Definitely a memorable dress of Katy's, it was one of the most talked about dresses at the MET Gala this year and it's not hard to see why. The LED lights and chiffon make for a very unique and beautiful dress, Katy looked fantastic.
6) Katy in Zuhair Murad:
Another one of those 'must've been made for her dresses', this Hervé Léger beauty is beautiful on her and the colour looks great against her tanned skin. Hervé dresses are definitely best on women with some curves that's when they really give their full effect.
