A person who sells ribbon and hat-making supplies is commonly referred to as a haberdasher. Haberdashers traditionally specialize in selling men's clothing and accessories, including hats, but the term can also encompass those who sell ribbons and other sewing materials. The word "haberdasher" originates from the Anglo-Norman French word "hapertas," meaning small ware or goods.
