The quarter-mile palm-tree-lined Worth Ave is Florida's answer to Rodeo Dr. It's lined with global brands: Cartier, Armani, Tiffany and so on. Tucked down side alleys, you'll find smaller independent purveyors and galleries. Half the shops close for summer, but it's fun to stroll and window-shop (and celeb-spot), whether you want to lay down your plastic or not. Royal Poinciana Way is an alternative (more reasonably priced) shopping hot spot.
