Fashion Face-off: Michelle vs. Ivana

Ooh, fashion disaster! Actress Michelle Trachtenberg and the former Mrs. Donald Trump, Ivana, showed up at the Just Cavalli flagship store opening in NYC on Friday -- wearing virtually the same dress!

While the former "Buffy" star looked slim and stylish in her deep green frock, Queen Ivana was literally bustin' out of her royal blue number. Czech, please!
