Red carpet style at the 85th Oscars

These women graced the Oscar's stage, gliding on the red carpet in all the very best designer gowns and dresses. 

Yes, "Argo," directed by Ben Affleck, won the top honor at the 85th annual Academy Awards on Sunday night in Los Angeles. But that's enough about the films.  

First Lady Michelle Obama appeared in style on the Academy's stage in a live video appearance from the White House, and of course, Hollywood's starlets were out and about. 

So who was the best dressed? And perhaps just as important, who was the worst?
