The "Pour It Up" singer started the evening baring just her back and midriff in a white Stella McCartney crop top and full length skirt on the red carpet for the famed Metropolitan Museum of Art's Costume Institute Gala.
But in true Rihanna fashion, the stunning singer decided it was time to leave a little less to the imagination, and made a quick costume change into a slinky gold number, with a very plunging back.
With an apparent lack of underwear, the superstar appeared perfectly confident posing for photos outside the exclusive bash.
Rihanna's zest for flesh isn't anything new. Last month she took sheer to a whole new level, showing her nipples in a see-through mesh top at the Balmain after-show party in Paris, France.
