+1 to MZhammer's advice. There is also a vast amount of information within StyleForum. The photo-heavy threads (such as the WAYW threads). As for actual books, there are quite a few. Manton, for example, wrote a book on men's style.As for unvented jackets, they may not be en vogue, but I wouldn't exactly say they're out of style. They create a different silhouette and look nice on the right body-type. They look great while standing, but not so much while sitting.
