The first one is my favorite. I'm dying for that cuff. It's vintage Seedhouse, which I can't find any information on, but apparently SJP wears their stuff a lot.
For the first outfit the top is Balmain and the skirt is Azzedine Alaia. For the second I think both pieces are Alexander Wang, or at least the top is.
I looked at the book yesterday, but I don't own it, so sorry if I am wrong.
