Casual Friday (also known asdress-down Friday orcasual day) is aWestern dress code trend in which businesses relax theirdress code on Fridays. Businesses that usually require employees to wearsuits,dress shirts,neckties, anddress shoes, may allow more casual orbusiness casual wear on such days.
In 1994, 497 of the 1000 most important companies in America observed casual Friday, includingGeneral Motors,Ford, andIBM.[1]
The trend originated fromHawaii's midcentury custom ofAloha Friday which slowly spread toCalifornia, continuing around the globe until the 1990s when it became known as Casual Friday. Casual Friday began in the United States in the 1950s and 1960s, whenHewlett-Packard allowed its employees to dress more casually on Friday and work on new ideas.[2]
In Hawaii, "Aloha Wear" is suitable business attire any day of the week, and the term "Aloha Friday" is generally used simply to refer to the last day of theworkweek.
Valerie Steele described the introduction of casual Friday as the most radical change in work fashion since the 70s, when women asked for the right to wear trousers in the office.[3]
