Powell later worked at retro menswear retailer Robot, managing the company’s outlet in
Covent Garden's Floral Street. In 1985, Powell opened his first shop in Soho's
Archer Street. Powell & Co initially sold unworn suits from the 1940s, 1950s and 1960s and then incorporated a tailoring business. Following the closure of Powell & Co, Powell operated from an atelier in Soho’s
D'Arblay Street. At this time, he worked with
Isabella Blow, who introduced Powell to
Bryan Ferry. In 1995, Ferry wore one of Powell's designs on the sleeve of his compilation
More Than This. Powell's suits were also worn for public events by British comedian
Vic Reeves and
George Michael. Powell's suits were also worn by
Bianca Jagger, and
Naomi Campbell. Powell also dressed and styled
George Clooney and
Harrison Ford when they appeared respectively as
Thomas Jefferson and
Abraham Lincoln on the covers of issues of
John F. Kennedy’s
George magazine. Cited in one case for his "attention to detail," Powell produced a series of collections for
Marks & Spencer’s Autograph range, and collaborated with fashion brands
Mulberry and
Michiko Koshino. During this time, Daniel Radcliffe wore Mark Powell suits for three of the London premieres of the
Harry Potter movies and British folk singer
Billy Bragg wore a suit from Powell on his 2007 UK tour. In June 2010, Powell opened the outlet Mark Powell Bespoke in Soho’s Marshall Street. Customers included
Bradley Wiggins, who mentioned that he conversed with
Paul Weller while they were both fitted for suits in the shop. Powell relocated his business to the Carnaby area of Soho in spring 2020 and began using
social media, as reported by Joshua Bluteau. ==Film and television==
