Pierre Cardin, born Pietro Costante Cardin (2 July 1922 – 29 December 2020), was an Italian-born naturalised-French fashion designer. He is known for what were his avant-garde style and Space Age designs. He preferred geometric shapes and motifs, often ignoring the female form. He advanced into unisex fashions, sometimes experimental, and not always practical. He founded his fashion house in 1950 and introduced the "bubble dress" in 1954.
