KEIRA KNIGHTLEY WEARS NEXT SEASON NOW

Of all the benefits being an A-list celebrity must bring, getting your hands on the newest designer buys well before they hit stores must be one of the greatest.

We've barely had time to digest the autumn 2010 shows and now the stars are already working the hottest looks straight off the catwalk. The latest star to make us green with envy? Keira Knightley.

The actress stepped onto the red carpet at last night's Lawrence Olivier awards wearing a floor length gown from Erdem'slatest collection, arguably our favourite from London Fashion Week. And, as if that wasn't bad enough, she looked stunning.

We're on the verge of throwing a fashion tantrum.
