This is Adorned Vanessa Perrin - she uses the Vanessa 3.0 sculpt, and is one of favorite dolls from the latest Integrity Toys convention (and the only one I've picked up). I loved the centerpiece Vanessa (1.0) doll, too, but she was a little pricey for my taste.
Her gown is lovely, though I'm not usually a fan of accentuating the articulation points of a doll, which is what often happens with super low necklines. The chiffon cape attaches to the dress in the back with a tiny button and two tiny magnetic clips at the shoulder, which I could not get working--but I often have a hard time with buckling shoes. No big surprise there.
Vanessa's auburn hair is probably really pretty when brushed out--but this is her right out of the box. I think it's meant to be a long Farrah Faucett style. I love her blue eyes with this look.
