I don't know what it is about Sienna Miller that allows her to get away with really sketchy style choices, and yet make them work. Now don't get me twisted. This Alexander McQueen dress that she wore to the 2014 Vanity Fair Oscars After Party is stunning — the drape, the colour, the 80s references — I love it. I also love the McQueen clutch. But those arm shackles are deeply disturbing. And yet...

Somehow, like with her messy barnet, she can make a slew of symmetrical brass armbands work on her. The fact that she has placed them so specifically tells you that a lot of thought went into just 'throwing this old thing on'. She definitely didn't just roll out of bed as her hair may suggest. But she looks glorious as ever. As does her scruff of an actor beau, Tom Sturridge. They really do look adorable together.

But you can't beat Sienna in a contemplative Mark Seliger Instagram shot...
