Hawaii is the only state in the United States that was once an independent with its own language and culture. Today, many Hawaiians continue to celebrate traditional Hawaiian holidays, such as Prince Kuhio Day, Kamehameha Day, and Aloha Week. In celebration of their Hawaiian ancestry, Islanders might dress in traditional clothes such as loose dresses called muumuus or colorful shirts. Around their necks they might wear leis, or rings of flowers.
