The Aloha shirt, commonly referred to as a Hawaiian shirt, is a style of dress shirt originating in Hawaii. It is currently the premier textile export of the Hawaii manufacturing industry. The dress shirts are printed, mostly short-sleeved, and collared. They usually have buttons, sometimes for the entire length of the dress shirt and sometimes just down to the chest (pullover). Aloha dress shirts usually have a left chest pocket sewn in, often with attention to ensure the printed pattern remains continuous. Aloha shirts may be worn by men or women; women's Aloha shirts usually have a lower-cut, v-neck style. The lower hem is straight since the shirts are not meant to be tucked in. (source)
