The Aloha shirt is a style of dress shirt originating in Hawaii.The shirts are printed, mostly short-sleeved, and collared. They usually have buttons, sometimes as a complete button-down shirt, and sometimes just down to the chest (pullover). Aloha shirts usually have a left chest pocket sewn in to make the printed pattern 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, as the shirts are not meant to be tucked in.
Aloha shirts exported to the mainland United States and elsewhere are called Hawaiian shirts and often brilliantly colored with floral patterns or generic Polynesian motifs and are worn as casual, informal wear.
