The Aloha shirt is a style of dress shirt originating in Hawaii. It is currently the premier textile export of the Hawaii manufacturing industry. 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.
By contrast, men's aloha shirts manufactured for local Hawaiian residents are usually adorned with traditional Hawaiian quilt designs, tapa designs, or simple floral patterns in more muted colors. Aloha shirts manufactured for local consumption are considered formal wear in business and government, and thus are regarded as equivalent to a shirt, coat, and tie (generally impractical in the warmer climate of Hawaii) in all but the most formal of settings. These shirts often are printed on the interior, resulting in the muted color on the exterior, and are called "reverse print"; this is often mistaken for the shirt being worn inside-out.
