If you're in the market for a menswear book that's more of a reference than a coffee table book, you're in luck. A new version of one of the most definitive books about menswear is about to be published. Originally written thirteen years ago by German author Bernhard Roetzel, "Gentleman: A Timeless Guide to Fashion" covers everything from formal wear, pajamas and deconstructing rugged outerwear staples like waxed canvas hunting jackets. The book is like poring through hours of menswear websites, forums and magazines in one sitting. Roetzel's rules offer some simple guidelines for guys who don't know their tattersall from their Prince of Wales check. And for men with a more individual sense of style, what better way to learn which rules to break than by having them all down pat in the first place? Pre-orders are currently being taken for a new hardcover version, releasing on November 15.
