Streetwear is a casual fashion trend that emerged in the 1990s. It features comfy yet fashionable attire such as graphic shirts, hoodies, sweatpants, and high-end footwear. Streetwear draws inspiration from hip-hop culture as well as skater fashion, with the addition of purposeful product scarcity. The term "streetwear" was first used by British magazine The Face to describe what now appears to be a mainstream adoption of hip hop clothing items by other youth cultures around the world. The streetwear fashion industry is a growing one; it is estimated to be worth over $1 billion per year. Major brands include Adidas, American Apparel, Anthropologie, Ben Sherman, Billionaire Boys Club, Brooklyn Industries, Caliroots, Champion, Supreme, and Umbro. Streetwear is defined by its lack of concern for traditional rules of style. Shirts often have large prints or bright colors, while denim is commonly worn with sneakers or boots. Accessories such as watches, chains, and scarves are also widely used. Hip hop musicians in the 1980s were known for their flashy clothes, which helped create the demand for streetwear. In the 1990s, popular brands such as Air Force One and Oakley helped spread the word about streetwear's identity as a cultural movement rather than a mere fashion trend. Today, major music festivals like Coachella and Lollapalooza feature exclusive designs by major brands.
