The 2009 Metropolitan Museum Costume Institute Gala honouring "The Model as Muse: Embodying Fashion" has officially begun! Catching our attention right off the bat is Rihanna who rocked up on the red carpet in this fabulous Dolce & Gabbana structured tuxedo from the autumn/winter '09 collection. Check out those cropped trousers, those dramatic puffed sleeves, those biker gloves! Rihanna didn't seem fazed by reports that she has cancelled her comeback tour, due to kick off in the United Arab Emirates later this month. Oh dear!
