I think this book is cute, more for young girls, even though they can't afford most of the stuff. In the back, there is a section for 'fashion credits' and it goes through page by page what clothing she is wearing, and you'll notice some of it is her own fashion line too. Some pieces are listed as unknown because they are vintage. It's a style guide so to speak and makes for a nice Christmas present.
Have you read Lauren's book? or any of her others?
