Streetwear is a style of casual clothing that gained global popularity in the 1990s. Emerging from the fusion of New York hip-hop fashion and Californian surf culture, it evolved to incorporate elements of sportswear, punk, skateboarding, 1980s nostalgia, and Japanese street fashion.

Streetwear is commonly linked to exclusivity, as many brands limit production through artificial scarcity to drive demand. This has led to practices such as limited edition releases and resale markets. In the 21st century, streetwear intersected with haute couture, as luxury fashion houses adopted streetwear influences, while streetwear brands incorporated aspects of high fashion including runway presentation, designer collaborations, and premium branding.
