It's been called "the Oscars of fashion," but the Costume Institute's annual fundraising ball at the Metropolitan Museum of Art has a different standard of dressing. For the A-listers who dare walk this most infamous and exciting New York City red carpet — casually known as the Met Gala — the bigger the risk, the brighter the flashbulbs. Some hew to the gala's theme; others choose to follow their own drumbeat. But those who have wowed keep one rule in mind: Never, ever be boring.
Take Rihanna, who in recent years has become the one to watch for her uniquely epic outfits. Pictured: At 2015's ball, themed "China: Through the Looking Glass," assistants carry her heavy train up the stairs of the gala. "Only women who have the confidence of a queen could wear it," said the dress' designer, Guo Pei.
