In the rest of Hawaii, dressing up might mean switching your flip-flops for shoes. But Oahu displays a contemporary, uniquely Hawaiian sense of style. There is so much shopping on Oahu, you could easily replace your entire wardrobe, furnish your apartment, and start a collection of Polynesian crafts. The Ala Moana Shopping Center, located beachfront right outside of Waikiki, is the largest outdoor shopping mall in the United States and a black hole of retail and restaurant options. The less congested Ward Warehouse (1050 Ala Moana Blvd, 808-591-8411) and Kahala Mall (4211 Waialae Ave., 808-732-7736) also offer one-stop shopping, mixing only-in-Hawaii boutiques with national brands.
Surfwear, bathing suits, and rash guards from local brands like Xcel or Hawaiian Island Creations make for very practical Hawaiian souvenirs. So do artisanal products from Island Glassworks or the network of galleries in Chinatown (check out First Fridays, an event that combines shopping and nightlife). And Hawaiiana books from Na Mea Hawaii or a real Kamaka ukulele are unique-to-Hawaii items you can't easily get anywhere else in the world.
