Born in Piacenza, Armani grew up during World War II in modest circumstances and initially pursued medical studies at the University of Milan before leaving to serve in the Italian Army. After his military service, Armani began his career in fashion as a window dresser and sales clerk at La Rinascente in Milan, later designing menswear for Nino Cerruti while freelancing for multiple manufacturers. In 1973, he partnered with Sergio Galeotti to open a design office and in 1975 they founded Giorgio Armani S.p.A., launching men’s and women’s ready-to-wear collections. Armani expanded his brand globally, introducing several lines including Emporio Armani, Armani Junior and AX Armani Exchange, while also establishing a presence in cosmetics, perfumes and home furnishings. His work in costume design for over 100 films, notably American Gigolo (1980), helped cement his international reputation.

Beyond fashion, Armani ventured into hotels, sports and music, including the Armani Hotel in Dubai, designing uniforms for Olympic and professional sports teams and curating Emporio Armani Caffè music compilations. He was an advocate for ethical practices, including banning underweight models in 2007 and promoting sustainable fashion initiatives. Armani maintained a private personal life, including a long-term partnership with Galeotti until the latter’s death in 1985.
