This Alexander McQueen dress is fetching on her — she could easily run across a field in an ad for feminine hygiene products in it, as violins swell romantically in the background — and her shoes are great. I wish she’d committed more completely to her hair, although it’s growing on me the more I look at it — no pun intended. My feeling is that because Sienna’s hair is so fine, the unbraided sides look less intentional and more like her braids are just falling out after a really intense SoulCycle. Which isn’t always what you’re going for on the red carpet.
