Hilary Swank, 2005: Swank won the best actress Oscar that night for "Million Dollar Baby" and the best dress award as well. The navy Guy Laroche dress is iconic for three things: it was long sleeved when most actresses wore sleeveless and strapless; it was navy silk jersey in a sea of black and sparkly bold color and it had no back, proving once and for all that your mom was right when she told you stand up straight.
