I know you've seen these pics, and I know I'm late, but no celebrity fashion blog worth it's salt can bypass the Metroplitan Museum of Art's Annual Costume Institute Gala. It is the fashion event of the year after all!

My favourite of the classic black gowns were worn by Zhang Ziyi, Blake Lively and Ashley Olsen.

Zhang Ziyi kept up on trends with a one shouldered black gown from Armani Prive Spring 2008 Couture, one of my favourites of the collection. Her sleek hair and clean skin were stunning.

Ashley Olsen looked way better than her sister Mary-Kate (who looked like an old lady with ashen skin, greyish hair and hunched shoulders) in a custom made Diane von Furstenberg cutout gown which looked sexy but classic. I wish she'd have put a little more effort into hair and make-up though.

My favourite black gown though was Gossip Girl Blake Lively's Ralph Lauren Fall 2008 gown. The strapless, feathered, fish tail gown fitted her like a glove and had just enough glamour whilst still being simple.

Her soft hair and make-up were flawless and the little black satin gloves were such a cute touch!
