When it comes to the subject of women's hat names, there is no one simple answer. For example, in the UK, a fascinator is a formal hat in millinery fashion. The phrase has been used to describe a formal headpiece worn in place of hats since the 1990s; it often consists of a sizable ornate design fastened to a band or clip. Other women’s hats have equally specific names that are largely based on the hat’s purpose or shape.
