15. Mellow Yellow
Rose Byrne donned a yellow satin Marc Jacobs dress to the 2009 MET Gala. Her spring 2009 dress was straight off the runway, and frankly that's where it should have stayed. The color of the dress was great, but it probably would have looked better on someone who was a bit taller. The flowing material made the star look slouchy, as if it was about to fall off her petite frame.
