2007: Sienna Miller
We LOVE a good flashback, and boy, do we have a good 'un for you! The best hair and makeup moments of the noughties (save for 2008 when the writer's strike got in the way). And January Jones, just in case you're reading this thinking, hang on a sec, my coral lipstick from 2009 was totally rad, why haven't I made the cut? It was (it still is) the best thing we have ever seen, but we feel you were pressured to live up to its awesomeness last year so we didn't want to say it again just in case you're getting all jittery wondering how on earth you're going to try and top it again this year. BTW how are you going to top it? Which star's past look is best?
