aloha shirts

The Aloha shirt, 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 cut from printed fabric. They are often worn untucked, but can be worn tucked in as well. They are not only casual wear, but serve as informal business attire in Hawaii.
"Aloha Friday", a now-common tradition of celebrating the end of the workweek by wearing more casual attire on Fridays, initially grew out of an effort to promote Aloha shirts.
