One is the hottest thing in reality TV and fashion. The other almost had a shot at becoming British royalty. So you know darn well that when these two young ladies battle it out in a fashion face-off, it's going down to the wire!
To the left, Lauren Conrad - the star of Laguna Beach and The Hills - poses for her new MARK Cosmetics ad campaign in midtown Manhattan this week. This All-American girl looks great, as usual. Missed your chance, Jason Wahler.
To the right, the newly single Kate Middleton at the Cheltenham Festival in England. The photo was taken back in mid-March, when she was still dating Prince William. Like LC, this British beauty wears the outfit stunningly.
Whose classy, trendy, yet sexy look is tops? You be the judge.
