Nice. I'm not very familiar with this line, but I like how they let the odd shape of the clothes + the fabric really take center stage. That makes sense for a former cashmere line.
I've been trying to figure out what she's preparing to do. Right now I'm leaning toward that oh so anxious moment when you're waiting around for a friend to show up to go out somewhere. You know. He/she's due at 3:00 and your clocks read 3:01, so you figure it's just a little fast because he/she COULDN'T POSSIBLY BE LATE. You also don't want to be seen standing right at the window ready to race out at first sight, so you can see that her foot is arched- ready to race away from the window. But you know soon she'll be out in that sunlight "showing off" the outfit to her friend.
Or you could go the sinister route and assume that she's been chased by some villain and is pray that he/she isn't on her trail anymore, but I prefer the lighter, more romantic plotline.
