Rihanna, Michelle Obama, Serena Williams, Maya Angelou, and more were honored last night as Glamour Magazine's Women of the Year. The annual ceremony celebrates women who have made meaningful contributions to sports, entertainment, business, fashion, science and politics. Of course for such a festive occasion, several well known stars came out in their most fashionable outfits.
Let's take a look:
Rihanna tearfully accepted her award in a floor length Stéphane Rolland Spring 2009 Couture gown.
Supermodel Iman fluttered on the red carpet in a peach feathered belted Jason Wu cocktail with matching platform sandals.

Serena Williams looked radiant in a Pamella Roland one shouldered red dress, as did Tyra Banks in a nude long sleeved shift.
Liya Kebede went for glam in a black Stella McCartney cocktail dress and strappy black sandals.

And Kerry Washington went for ethereal and light in a Fendi lace maxi dress.
