When it comes to high-stakes, high-fashion events, nothing compares to the Metropolitan Museum of Art's annual Costume Institute Gala. The ridiculously glamorous benefit always draws the creme de la creme of the glitterati and invariably produces the most intriguing red carpet of the year. Monday's soiree lived up to this reputation, as celebrities, models, and designers turned out in droves to celebrate 2010's exhibition—
American Woman: Fashioning a National Identity. Co-hosted by Oprah Winfrey, who was resplendent in a custom Oscar de la Renta navy silk organza embroidered gown, Gap's Patrick Robinson, and
Vogue's Anna Wintour, the Met Gala attendees toasted American style in a most memorable way. We've gathered a few of our favorite looks of the night for your viewing pleasure, ranging from Chloe Sevigny's flawless teal frock to Alexa Chung's modern tuxedo. Read on for all the details and don't forget to tell us which ensembles you liked best—and why! (We always love to hear your thoughts.)
