Charles Tyrwhitt (also known as CT Shirts) is a multi-channel British clothing retailer, specialising in men’s shirts, shoes, suits, knitwear, and accessories, with some lines of womenswear. Charles Tyrwhitt was founded as a mail order company in 1986 by Nicholas Charles Tyrwhitt Wheeler while he was a student at Bristol University. Wheeler has said that he started the business simply because he thought he "could make a shirt better than anybody else". In 1997, the company opened its first store on Jermyn Street, London, notable for its history in British shirt making. Charles Tyrwhitt’s flagship store is now at Nos. 98–100 Jermyn Street. Charles Tyrwhitt uses a high-low pricing sales model. His wife, Chrissie Rucker, is the founder and owner of The White Company.
