Hats off to Kate Middleton. The new Duchess of Cambridge has sparked a trend in hat accessories called fascinators, say industry observers and entrepreneurs who specialize in the niche. Fascinators are decorative trappings made of fanciful materials such as feathers, flowers, lace or beads. They're typically attached to hats or worn in one's hair in lieu of a hat, along with formal attire. Some American hat retailers say the accouterments have been selling strong ever since photos of Ms. Middleton wearing them began to surface a few months ago. Customers are mostly brides and fans of the Kentucky Derby, the annual race that's populated by attendees donning frivolous, oversized hats/Sarah E. Needleman, Wall Street Journal. More here.
