Keira Knightley ended up having 3 looks last yesterday to promote “Last Night” during the 2010 Rome Film Festival.

For the photocall she wore Chanel.

To the premiere she wore Valentino and for the dinner party she wore Chanel again.

I loved that she totally stripped down her Chanel Spring 2011 black and grey ensemble and made it as effortless and simple as possible.

The black pumps totally work on this rare occasion for me.

I think I prefer this look to the photocall look.

Classic Keira.
