Rihanna's Red Carpet comeback at Costume Institute Gala 2009

Rihanna made her first red carpet appearance last night at the annual Met Gala benefit and, wow, what in the... I mean it is the Costume Institute of The Metropolitan Museum Gala.

So she was stunning... even with her 80's shoulder pads.

She wore a black silk Tuxedo inspired suit - Black capri pants, white dress shirt under a jacket with extra puffy shoulders and gathered sleeves and bow tie. She accessorized with stud earrings, leather gloves and black statement heels.

Her hair was swept to a side with prominent platinum blond highlights and she wore blue eye shadow that extended beyond her eyelids.

Rihanna later attended Marc Jacobs after-party at 'Monkey Bar' in New York City, where she hung out with Katy Perry.

Other celebrities at the event included Madonna, Kate Hudson, Anne Hathaway, Eva Longoria with husband Tony Parker, Kate Beckinsale, Kate Moss, Jessica Biel with Justin Timberlake and Victoria Beckham.

The Metropolitan Museum of Art is one of the world's largest and most important art museums, located on the eastern edge of Central Park in Manhattan, New York.

Its Costume Institute contains more than 80,000 costumes and accessories. Due to the fragile nature of the items in the collection, the Costume Institute does not maintain a permanent installation. Instead, every year it holds two separate shows in the Met's galleries using costumes from its collection, with each show centering on a specific designer or theme.
