God love Michelle Williams for single-handedly making the crop the most desired it has been since the Audrey days. Sure Halle put in the hard yards, but Michelle is modernising it (or retro-nising it, I guess) and wearing it with flair and that certain je ne sais quoi needed to carry off the shorter style. Case in point: the screening of Blue Valentine in London during the BFI London Film Festival on Friday night. She's still rocking the mega-peroxide hue that she debuted in Cannes earlier this year, complete with darker brows. But by working product through the front and turning the style into a quiff, it's taken it to a top crop, dontcha think?
