haberdasher
A merchant who sells men's accessories and small articles of dress, such as ties, gloves, hats, and handkerchiefs. This is a formal, somewhat dated term; in modern Japanese, 紳士服店 or メンズショップ are more common for a men's clothing store.
My grandfather used to run a small shop as a haberdasher.
