Save for the Nordstrom book, you've got a good, solid collection there. You'll find the most value at the margin from the following tomes in descending order of utility: Francois Chaille, The Book of Ties (Flammarian, 1994). There isn't a lot to know about suits when it comes right down to it. There are only a few choices to make and it's pretty easy to navigate those choices with the books you have. But how to best match a shirt and tie - particularly the tie! - with the same is the real art of dressing. This book goes into great depth on this subject; more than anything else out there that I am aware of. While this is more history and survey than a "how to dress" guide, it offers valuable thoughts on that subject. Riccardo Villarosa & Giuliano Angeli, The Elegant Man: How to Construct the Ideal Wardrobe (Random House, 1990) - One of the very best books on the subject and also covering ground - particularly regarding fabrics - only lightly covered by your other books. Alan Flusser, Clothes and the Man: The Principles of Fine Men's Dress (Villard, 1985). Many argue this is a better book than Dressing the Man, but I'm not so sure. There are a some issues addressed here - like what an ideal businessman's wardrobe might look like as far as suits, shirts, and ties are concerned - that are not addressed by Flusser in his most recent tome, and some other areas that get a bit more attention here than there. But there are other issues - like personal color considerations and pattern matching - that got more attention in Dressing the Man. Hence, it's worthwhile I think to get both despite the large degree of overlap. Eric Musgrave, Sharp Suits (Pavilion, 2009). Light on text but heavy on inspirational photographs. Much can be learned here regarding style by just thumbing through this beautiful and reasonably thick coffee table book. G. Bruce Boyer, Elegance: A Guide to Quality in Menswear (W.W. Norton, 1985). A collection of Boyers' essays on menswear from Town & Country. He goes into a some depth on issues that get only cursory attention elsewhere. For instance, there are thoughtful and intelligent essays here on double-breasted suits, seersucker suits, Italian style, etc. You will find some areas of disagreement between Boyer and some of the other style icons out there like Alan Flusser (for instance, regarding shirt collar guidelines), but not too many. Hardy Amies, ABC of Men's Fashion (Abrams, 2007). An interesting albeit idiosyncratic take on men's fashion and classical style originally published in 1964. Lots of useful advice on oft-overlooked matters and arguments regarding color and wardrobe construction that you won't find anywhere else. Of course, that might have something to do with the fact that Amies' views are ... idiosyncratic. But they are interesting and informed. Paul Keers, A Gentleman's Wardrobe: Classic Clothes and the Modern Man (Weidenfeld & Nicolson, 1987). Another book that covers the soup-to-nuts Flusser and Roetzel ground but whereas Flusser comes at this with an American take and Roetzel from a continental angle, Keers brings a distinct English sensibility to these issues. The result is a somewhat different set of opinions about many matters but nothing too terribly at odds with the rest. There are some interesting opinions offered here and there, however, that you won't find too often elsewhere (but not quite as many idiosyncratic bon mots as might be found in Amies). G. Bruce Boyer, Eminently Suitable (W.W. Norton, 1990). Covering the same issues covered by Manton's The Suit but with somewhat different angles at times. No fundamental disagreements between the two, however. Until The Suit, this was the book on the subject. Now, it's mostly overlap. Had The Suit not been published, this would have been at the top of my list. It's less useful to you now, however, but if you are obsessive on the topic, then you will want this for footnotes to Manton. There are a couple of other books on two rather inspirational style icons that will be quite useful depending upon your personal style: Richard Torregrossa, Cary Grant: A Celebration of Style (Bulfinch Press, 2006). The book has been criticized by some for being a bit frothy and inaccurate, and while there is some truth to that, it is still a useful tome on how to make Grant's elegant simplicity work for you. If you like his style - or James Bond's or Douglas Fairbanks' or Gianni Agnelli's - then this book will help show you how to do it. And it will also tell you about Grant's life and personality and that's always a delightful matter to chew over. G. Bruce Boyer, Fred Astaire Style (Assouline, 2004). As above but without the criticism for occasional inaccuracies. Short but sweet. Astaire has an entirely different look than the icons mentioned above but he is their equal in every way. Very heavy on inspirational photos but light on text. Still worth getting IMO. There are a few others out there worth reading if you're an obsessive, but these will give you the most to chew over.
