Doormen dressed as pirates or pharaohs work the front entrances, and cocktail servers stroll the casinos like so many glittering Hollywood starlets or kohl-eyed Egyptian queens. In Las Vegas, what hotel staffers wear is more theatrical costume than uniform, another opportunity to restate and expand on the house fantasy. Still, form must follow function when designing these elaborate outfits. "We have to cater to a broad range of figures. Real people, not models, wear these clothes," says Joan Poggioli of Poggioli Design in New York, who created the costumes for the 7,000 employees at Luxor and Excalibur. "We build in adjustable features, like Velcro waistbands." At Treasure Island, gold buckles come with elastic bands that are guaranteed to fit any shoe, from sneakers to wingtips.
