There’s a certain type of impeccably dressed gentleman for whom Arnys is the only Paris address one needs. The 76-year-old Left Bank institution is a one-stop emporium for men who prefer their fabrics Irish and their tailoring soft-shouldered and hand-sewn. (Clients have included former French president François Mitterand, the current prime minister François Fillon, and Yves Saint Laurent.) The ready-to-wear collection, located on the ground floor, mixes tailored suits with vintage watches, formal shoes, and socks in about 100 hues. On the second floor, up a grand cast-iron staircase, lie the bespoke salon and two tailoring ateliers. And though it’s just a few steps from the department store Le Bon Marché, there are no designer names here—no Prada, Armani, Zegna—just Arnys’s own private-label classics, like the La Forestière blazer (from $1,125), based on a 19th-century workman’s uniform and originally created for Le Corbusier in 1947, and the signature seven-fold tie, made from a single square of silk. Each print is produced in a limited quantity of just 40. At 14 Rue de Sèvres; 33-1/45-48-76-99; arnys.fr.
This Marais shop features relaxed—if a bit avant-garde—pieces, from Scandinavian labels like Filippa K and Acne to cutting-edge designer collectives such as Opening Ceremony. 116 Rue Vieille du Temple; 33-1/44-61-00-14; frenchtrotters.fr.
This store may be an offshoot of a hipper-than-thou record label, but its take on quality is quite traditional: French leather, Italian cashmere, Japanese denim. 52 Rue de Richelieu; 33-1/42-60-34-28; maisonkitsune.fr.
Designer Philippe Alvergne reworks classic men’s staples: Chinos find the right hipster-aristo balance; tweed jackets are cut desirably slim; and cardigans are perfectly chunky yet entirely flattering. 11 Rue du Perche; 33-1/42-74-15-35; tremblay-alvergne.com.
