Charles Suppon

Charles Suppon (1949-1989) was an American fashion designer.

Suppon was born in Collinsville, Illinois in 1949, and studied in Chicago. He came to New York and began working for Calvin Klein as an assistant on the recommendation of Chester Weinberg, before leaving in 1976 to work for Intre Sport. He designed both menswear and womenswear, specializing in sporty clothes such as easy-fitting dresses and men's mohair sweatsuits. In 1979, he began creating performance costumes for Peter Allen, starting with the one-man revue Up in One. The musical, the only one Suppon worked on, failed to be critically well-received, and closed after 64 performances.

By the time Legs Diamond was in production, Suppon had been getting sicker and sicker,

Some of Suppon's archives from his time at Intre Sport are held by The New School.
