Ashlee Simpson vs. Katy Perry in Temperley London – Fashion Face-Off! Who Wore It Better?

It’s a battle of the ivory gown!

Ashlee Simpson looked statuesque in this stunning Temperley London while attending HBO’s 2012 Emmy Awards Post Awards Reception last month while Katy Perry wore the same dress back in April while attending the 29th Annual ASCAP Pop Music Awards.

Ashlee takes it home in this face-off, I find Katy’s falling strap looks a little slobbish.

Who do you think wore it better? Sound off in comments below or let me know on Facebook or Twitter!
