Fascinator: a hairpiece, a style of millinery like a hat, also called a cocktail hat, commonly made with feathers, flowers and beads. Fascinators are popular at events where hats were traditionally worn, such as horse-racing events, as an alternative.
Although this term fell into disuse by the 1970s, it is used in a newspaper article referring to hairpieces worn by women at church at St. James Cathedral in Toronto, Canada today.
The Queen is noted for her hats, and she was certainly not upstaged. But there were quite a few women in the church who also wore hats and fascinators.
Silk flowers, too can be just the perfect finishing touch for a coat or suit or even a dress.
