Hollywood's fashionistas gathered at Lincoln Center's Alice Tully Hall to honor some of the industry's biggest fashion designers at the 2011 CFDA (Council of Fashion Designers of America) Awards in NYC Monday night.

The event, which was sponsored by Swarovski, recognizes designers, icons, and journalists for their contributions to the fashion industry. See more pics from the CFDA Fashion Awards.

Some highlights from the night: Lady Gaga, who attended with her parents and sister, received the Fashion Icon Award; Marc Jacobs was given the Geoffrey Beene Lifetime Achievement Award; Mary-Kate and Ashley Olsen were among the nominees for the Swarovski Award for Womenswear, but lost out to designer Prabal Gurung (who designed Victoria's Secret model Alessandra Ambrosio's gown for the night).
