DO-RAG

A 'do-rag', also spelled 'doo-rag,' 'du-rag,' 'durag,' ''wave cap' or 'watchu-rag' is a piece of cloth used to cover the head.
The do-rag was popular throughout many different eras. In the 1930s women wore bandana like fabric to fasten their hairstyles in place while they set. In the 1940s the style among women shifted into the workplace where they were taking over factory jobs and needed a safe way to keep their hair out of the machinery. Rosie the Riveter is famously featured wearing the blue-collar woman's do-rag.
From the 1930s to the 1960s, they were used by African-American men to hold chemically processed hair-dos in place while they slept. Originally they were made from pieces of handkerchief, bandanas, or women's stockings; now they are made from polyester. Do-rags resurged as a fashion trend among urban youth in the 1970s and 2000s. Do-rags are worn in a variety of colors, with black being the most common. Do-rags are regularly used to create and maintain waves. They are also used for cornrowed hairstyles. It usually has ling ties on either side which are wrapped around the head to secure the do-rag and tied at the back.
Hip hop artists such as Chamillionaire, LL Cool J, Sheek Louch, Mike Jones, Petey Pablo, 50 Cent and Cam'ron have helped popularize do-rags among mainstream audiences by incorporating them in their dress. It is also popular for breakdancers to wear do-rags as a fashion.
Do-rags are also popular among motorcycle riders. The do-rag is worn by a rider as a way to keep hair from blowing into the face and eyes while riding (a benefit to both the rider and to any passenger they may have riding on their bike behind them), as a way of keeping bugs out of the hair, and as a way to absorb sweat. Generally, riders who use a do-rag for these purposes do not also wear a motorcycle helmet. Though the majority of motorcyclists prefer the original bandana.
Some gang members may wear do-rags representing their gang colors.
