Richmond moved from Manchester to London, then eventually to Milan to pursue his dreams. He graduated in fashion design from Kingston University in 1982, and straight away designed his own collection under his own name, while collaborating with such brands as Armani, Joseph Tricot and Fiorucci.
In 1984 he formed The Richmond-Cornejo label with Ravensbourne graduate Maria Cornejo. Since 1987, Richmond has worked under his own name producing three lines, the main line: John Richmond, second line: Richmond X, and the denim line: Richmond Denim.
His close ties with the rock music fashion industry have led him to dress stars such as Madonna, George Michael, David Bowie, Mick Jagger, Annie Lennox, Axl Rose, Bryan Adams, David A. Stewart, Michael Jackson, Britney Spears, Kim Kardashian, Dita Von Teese, Kate Moss, Kaya Jones and also former Milano footballers: Marco Materazzi and Clarence Seedorf.
