I love fashion books, and makeover books, and style books, particularly style books, and this is a wonderful addition to my collection. This is more of a workbook than a picture book, because it's about helping you make your own, personal picture book about your own personal style. I haven't worked through it, because it's something that will take time, with many small steps from finding your current style, finding out what it is that you want your style to be, and working towards that goal.
One of my favorite things is identifying where you are now. I've never seen this step displayed as an important step, but it seems apparent that you can't know where you're going if you don't know where you've been. The entire tone of the book is so not consumerist, it's a relief! I don't feel like there's some 'out there', 'other' that she's selling, only that she wants you to be the happiest you possible.
One thing I would suggest for anyone really interested in finding their personal body shape is making a croquis. This is where you dress in a leotard or underwear and take photos of yourself front, side and back, then use it as a paper doll, printing it out so you can try out different silhouettes and styles. This is something I learned as a sewer, and I find it incredibly helpful, not only because you can use it as a fashion piece, but I think that the more exposure you have to your actual body, the less abhorrent you find it; the first time I made a body form, my body form, I was appalled how huge and three dimensional it is because I only see mirror images/photos of myself, but to have an actual figure that takes up space was a shock. Eventually familiarity made the size acceptable to me.
