Simplex Munditiis, Gentleman by Mortimer Delano de Lannoy is a guidebook to how one should dress. Excerpt: «Proud, indeed, may the man be who can write after his name—gentleman. Let “Simplex Munditiis” be your motto for a dress. Each person must remember one thing: that, to be distingué in dress, he must dress, as regards material, richly; and, as to the pattern of cloth. In other words, simple elegance shows the gentleman. Everything you wear must be immaculate.”
