This huge and magisterial book is by Hugo Jacomet who founded The Parisian Gentleman* blog which looks at the best of men's style all over the world. The book seeks out some very well-known names and many much less-known and introduces us to the delights of Paris as a centre of menswear excellence.
The profundity of my ignorance is such that I find that many of what I thought were Italian are in fact Parisian businesses (like Berluti, Camps De Luca and Cifonelli) and it's fascinating to read their histories. The huge illustrations are high quality and beautifully presented.
From the best of tailoring to shoes, fragrances and accessories, this is a fascinating and educational book for any man with even a passing interest in style and quality. See Thames & Hudson.
