Aww! Isn't that sweet, Sienna Miller is wearing sunglasses at night, just like Anna Wintour! It's the blind leading the blind! Literally.
The dark glassed duo were attending a screening of The September Issue, the documentary about Vogue. It's one of the most eagerly anticipated films of the year for the fashion world, and so naturally Anna would've been keen to have a true style icon in attendance. Such a shame that none were available and she had to bring Sienna, instead! (Joking! We're joking!)
You'll find more fashion from The September issue screening under the jump. Whose look do you like best?
