1. Leonard Logsdail — East 57th Street, Midtown, Manhattan
True bespoke by the strict definition — the man who measures you is the man who cuts the cloth.
Leonard Logsdail works from a fourth-floor workroom in Midtown and is unusually explicit about what bespoke means: the garment is cut by the person who measured you, an art that cannot be replicated and is only possible after years of training. That is the strict English definition, and very few houses in America can make the claim honestly.
The practice runs US trunk shows alongside the New York workroom, and there is now a ready-to-wear collection for clients who want the house's shapes without the commission. For a suit meant to last decades and be altered as you change, this is the reference point in the city.
Good to know: If you cannot get to Midtown, check the trunk show schedule — the workroom travels, and a first measurement can often happen closer to home.
