Whoops. Didn't see that you were looking for the brand it was taken from. I believe that it is a Victorian Maiden style coat, but that is not one of their photos. I think that the photo was actually taken by the maker themselves of their work. Though, I have heard stories about this sellers quality and it does NOT measure up to their photography. They do shody work.

It's a summer coat and the only one up right now, so it's not exactly the same, but you'll see what I mean about the cut:
However, yes, that is quite a common cut for lolita coats. But usually Baby uses more fur, or puffier? fur on the collar and Angelic Pretty has more bells and whistles. In the end, it's pretty generic.
