Pop Quiz: Red Carpet Fashion!

Who first wore Reese's infamous Chanel frock? How many times did Beyonce change at the Oscars? Test your fashion memory! By Caryn Midler and Brian Orloff

Q: 1 of 6

The fashion faux pas was revealed the day after Witherspoon won for Walk the Line, when photos surfaced of Kirsten Dunst in the same "vintage" dress (at a 2003 Golden Globes afterparty, no less!). So for the Oscars, Witherspoon played it safe – going all the way to Paris to buy a one-of-a-kind 1950s Dior.
