Two days ago Anna visited David Letterman on his Late Show to talk about fashion, The September Issue movie and Fashion's Night Out. I don't think she did a good job there, but Letterman was even worse (I have this feeling he was afraid of her(?)).
Anyway, she's mentioned an interesting thing - this whole NY Fashion's Night Out, which is basically supposed to be a massive shopping spree. After seeing the movie above, I found this ad of the already famous night featuring Vera Wang, P. Diddy, Carolina Herrera, Coco Rocha, Donna Karan, Ashley Olsen, Diane Von Furstenberg and Anna, of course. But... watch out - she is wearing a t-shirt!
