Fashion's finest descended on Lincoln Center in NYC on Monday evening for the CFDA Fashion Awards. Stars like Lupita Nyong'o, Blake Lively , Olivia Wilde , and Marion Cotillard walked the red carpet in gorgeous outfits by their respective designer dates for the annual event, which was hosted by film director and screenwriter John Waters. Lupita, who presented the womenswear designer of the year award during the ceremony, made her CFDA debut in a printed top and matching shorts, while Blake kept things short and sweet in a beaded Michael Kors  minidress and '60s-inspired beauty look. It was Rihanna , though, who may have stolen the show; she hit the scene in a revealing sheer beaded gown for her big night. She was honored with the fashion icon award this evening and showed off her signature edgy style while posing for photos with a fur stole all night long (don't worry, she was wearing underwear!). Also on hand for the high-profile event were models Karlie Kloss, Alessandra Ambrosio, and Chanel Iman as well as designers Diane von Furstenberg , Betsey Johnson , and Rachel Zoe , who walked the carpet with husband Rodger Berman. Elsewhere, comedian Chris Kattan reprised the role of his infamous SNL character Mango, popping up for the event in a black cape and shorts.
The annual CFDA event honors American designers for their contributions to the fashion industry in categories including womenswear, menswear, and accessories. Some of the night's nominees included Marc Jacobs , Alexander Wang , and Mary-Kate and Ashley Olsen , who picked up the top prize for womenswear in 2012 and won accessories of the year on Monday night.
