Sumrie House was a British company specializing in the production of high-class ready-to-wear clothing and bespoke tailoring, It was famous for developing a process for creating garments in 100 different sizes, thus providing the first ready-to-wear garment to the London market, and establishing Leeds as the center of ready-to-wear British fashion. The pioneering men's fashion textile company, C. and M. Sumrie Ltd was founded in 1891 in Leeds by Harris SUMRIE (1866–1951) who was a Polish, Jewish immigrant from Russian Empire in 1886, with his wife Malka TULINSKY (1860–1926). Harris was a skilled tailor himself, in 1911 he was operating a bay-windowed house in Exmouth Grove, Leeds, as a coat maker and tailor. By 1919, he employed around 35 people. During World War I, the business grew rapidly and in 1921 it moved with 250 employees to new building on Woerth Place, Camp Road. In 1922 Harris SUMRIE registered his clothing line trademark. In 1924 he opened another factory at Stamford Works, Cross Stamford Street, with 300 employees. In 1932, the business became a private company. In May 1934, a new factory, called Sumrie House on York Road, was opened in Leeds. The sewing machines were supplied by The Bellow Machine Co. and the pressing machines by Hoffman Presses, made by Isaac Braithwaite & Son of Kendal and Leeds, Messrs. Mason and Co. were responsible for the showroom, featuring garments for the season ahead. In that moment the business employed 1,300 people. At Sumrie House, there was a team of designers who worked on perfecting garment fit – 70 models were employed to provide garments in 70 different sizes.
