Do you have a favorite book about style, fashion, or beauty?

My favorite is The Triumph of Individual Style ( But I will also confess that it is the only style book I have read to date! :^) I liked it because it was built around examining your own body and how you can "echo" your own body traits in your clothing. For example, the authors have you analyze your facial structure to see if you have generally straight lines or curvy ones, and they show you how you can echo this in clothing details. They also show how you can mimic your bone structure (large, medium, or small) in your choice of handbag, jewelry, and footwear. In short, it provided me with a lot of new ways to think about clothing.
