The headquarters of the Diesel denim brand is located in Breganze, Italy.
Diesel was founded in 1978 by Renzo Rosso, who began the company in the Italian province of Vicenza. Breganze, a town in the Veneto region, became the company’s base and remains closely associated with the brand’s corporate identity.
Diesel built its reputation through unconventional denim washes, experimental treatments, and advertising that positioned jeans as fashion rather than only workwear. The company’s international name also helped distinguish it from more traditional American and European denim labels.
Breganze is sometimes confused with larger Italian fashion centers such as Milan or Florence. Those cities are strongly associated with Italian fashion, but Diesel’s headquarters are in the smaller Veneto town. Diesel later became part of the OTB group, the fashion holding company founded by Rosso.
