A woman typically wears a pin on the left side of her clothing, at the height of a breast pocket. Pins are worn straight to exude professionalism and in a line down the left side if there is more than one.
Lapel pins and brooches are worn with professional attire such as pants suits, dresses or jackets. Usually, one pin is worn at a time for a tidy appearance. Decorative brooches are also used as jacket fasteners in the middle of a light coat, blazer or shawl. Brooches are also used as decorations on items such as purses and bags.
