I found this book disappointing. There aren't many photos in the first half of the book at all, which is a little strange when fashion and style are such visual entities. The problem is, there's a lot of writing, some of it useful, but much of it boring and not at all helpful or even interesting (or at least, I didn't think so).
The authors' tone grated on me at times as well; it's very much in the style of 'I'm the fashion expert and you're the clueless fashion victim', and is full of Americanisms. Personally, I've got a very clear sense of my clothing style, as I'm sure other readers of these kinds of books have - we read them because we love the creativity and expression of clothes, shoes and accessories, and enjoy reading other peoples' views on style/seeing photographic examples.
For that reason, I'm quite a fan of fashion/style books, but this one left me feeling uninspired.
