FASCINATOR
A fascinator is a headpiece, a style of millinery. The word originally referred to a fine, lacy head covering akin to a shawl and made from wool or lace, but mostly feathers. In the modern usage, it refers to a woman’s alternative to hat for formal attire; it is usually a large hair decoration on a band or clip with elaborate trimmings and decoration like a formal hat and it can incorporate a base to make it a miniature hat.
