I liked this book although not as much as the original series. The girls in the book are only 14 and seem young to me to be doing some of the things the author has them doing. At least we didn't do those kinds of things when I was 14 (granted that was more than 20 years ago). I also didn't like the fact that the author took a minor character from the original series and turned her into the main "bad guy" of this book. It seemed very contrived to me - it really wasn't necessary that the "nasty girl" character be someone from the previous books.
Basically even though I liked the book I would say that I didn't find it as believable as the original Sisterhood series.
Like many of my clothing purchases, this book was an impulse buy, and one I will not regret! I read this book through in just a couple of hours and totally got into it. Fun, entertaining, and informative on the world of vintage fashion. By the time I was done with it I was ready to go on a shopping spree!
