Streetwear is a style of casual clothing which became global in the 1990s. It grew from New York hip hop fashion and Californian surf culture to encompass elements of sportswear, punk, skateboarding and Japanese street fashion. Eventually haute couture became an influence. It commonly centers on "casual, comfortable pieces such as jeans, T-shirts, baseball caps, and sneakers", and exclusivity through intentional product scarcity. Enthusiasts follow particular brands and try to obtain limited edition releases. History Streetwear style is generally accepted to have been born out of the New York City hip-hop culture of the late 1970s and early 1980s, with elements of Los Angeles surf culture. Early streetwear in the 1970s and 1980s also took inspiration from the do-it-yourself aesthetic of punk, Japanese street fashion, new wave, heavy metal, and established legacy sportswear and workwear fashion brands such as Schott NYC, Dr. Martens, Kangol, Fila and Adidas. In the late 1980s, surfboard designer Shawn Stussy began selling printed T-shirts featuring the same trademark signature he placed on his custom surfboards. Initially selling the items from his own car, Stussy expanded sales to boutiques once popularity increased. Then as sales peaked, Stüssy moved into exclusive sales to create product scarcity, which established streetwear's focus on T-shirts and exclusivity. In the early 1990s, burgeoning record labels associated with popular hip-hop acts like Tommy Boy Records, Def Jam Recordings, and Delicious Vinyl began selling branded merchandise embroidered onto letterman and workwear jackets made by companies like Carhartt. By mid-decade, influences included skateboarding and gangsta rap. Professional American sports franchises have had a significant impact on the scene, especially the New York Yankees, Los Angeles Raiders and Chicago Bulls caps and jackets, with their production of oversized team jerseys, as well as boots from The Timberland Company and the latest shoe design releases from Nike, Inc. Brand launches by the chief executives of record companies followed, with Russell Simmons of Def Jam launching his Phat Farm label, Sean Combs of Bad Boy with Sean John, and Jay-Z and Damon Dash of Roc-a-Fella Records launching Rocawear. Luxury sportswear Jil Sander was the earliest fashion brand to collaborate with a sportswear firm, Adidas, on a co-creation project in 1998. Since then, the advent of "bling" culture saw established luxury brands make inroads into the market, with Burberry, Gucci and Fendi making appearances in films and hip hop videos.
