noun
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.
祖父は昔、紳士用装身具商人として小さな店を営んでいた。
My grandfather used to run a small shop as a haberdasher.
Compound of 紳士用 (for gentlemen) + 装身具 (accessories) + 商人 (merchant). The exact historical derivation is uncertain; the term likely emerged in the early 20th century to describe a specialized retailer of men's accessories.
