The aloha shirt (Hawaiian: palaka aloha), also referred to as a Hawaiian shirt, is a style of dress shirt originating in Hawaii. They are collared and buttoned dress shirts, usually short-sleeved and made from printed fabric. They are traditionally worn untucked, but can be worn tucked into the waist of trousers. If you've ever been to Hawaii or any other tropical location, you've probably noticed locals and tourist alike sporting colorful, flowery, and vibrant shirts. These shirts are often referred to as Hawaiian or Aloha shirts. While many people use these terms interchangeably, there are small differences that distinguish the two shirt styles.
