Fashion round-up: The Costume Institute Gala

Fashion hits and misses at the style industry's biggest night of the year

This year's Metropolitan Museum of Art Costume Institute Gala was entitled The Model as Muse, so it was only fitting that the night's host, Kate Moss, should utterly embody the evening's theme.

Joining Marc Jacobs and Justin Timberlake, the super hosted the star-studded soiree, and well and truly stole the crown as the evening's ultimate style muse, in a gold lamé gown by Jacobs and a Stephen Jones turban. A look that few could pull off, but on Kate it looked simply sublime.

The model style hits just kept on coming. With every supermodel under the sun taking their seat – Cindy Crawford, Amber Valetta, Agyness Deyn, Bar Refaeli, Claudia Schiffer, to name just a few - the evening was a veritable feast of fashion faces.

As for who was joining La Moss at the top of the best dressed list, Diane Kruger was ethereal in a white Chanel minidress, while Stella McCartney scored a style hat trick, with Kate Bosworth, Kate Hudson and Liv Tyler proving the perfect poster girls, all wowing in her designs.

And then there were the bad. The most stylish night of the year drew some sartorial shockers.

Topping the list, Madonna drew gasps for all the wrong reasons, appearing to have raided her 1980s dressing-up box. The fingerless gloves, poof-ball minidress and antenna-style scrunchie all screamed circa Like a Virgin. You may have a twenty-something on your arm Madge, but that doesn't require reverting to your twenty-something wardrobe!

They may be rising style stars, but Leighton Meester and Mary-Kate Olsen were also seriously disappointing. In a look that would horrify her perfectly preened Gossip Girl alter ego, Meester was nauseatingly miss-matched. Her printed minidress alone we could stomach, but add co-ordinating leggings, a poodle perm 'do, and bizarre ankle-strap sandals and we have a couture car crash.

As for Mary-Kate, and we only need two words – Eighties bridesmaid. Do you see where we're coming from?
