Early years – S Simpson

In 1894 Simeon Simpson, aged 16, rented a room on Middlesex Street, East London, with the intention of setting up a business in bespoke tailoring, focused on high standard craftsmanship.^[2] Several innovations of technology at the time were being introduced with machinery capable of making buttonholes and electric powered saws to cut many layers of fabric at once; Simpson saw the potential for such equipment for producing garments in higher quantities while still upholding quality tailoring techniques, aiming to improve ready-to-wear standards as no male or female professionals considered ready-to-wear to be suitable attire at the time.^[3]: 2 Simpson's methods proved successful in speeding up the process and he set up several factories within London, which soon required expansion in its early years through popularity of the label.^[3]: 1–2

Alexander Simpson, his second son, joined the business aged 15 in 1917, and by 1929 had planned and opened a larger factory in Stoke Newington where production could be centralised, this again had to be enlarged a few years later.^[3]: 3

20th century – DAKS and Simpsons Piccadilly

With the continued growth of the company Alexander Simpson began to take more control of the business, and in 1935 DAKS tailored the first self-supporting trouser.^[4] The trousers were available in many colours and fabrics that weren't generally associated with menswear. Soon after a DAKS womenswear line was released, using the patented waistband for skirting.^[3]: 52

At the turn of the 21st century when the company was acquired by Japanese group Sankyo Seiko Co. Limited in 1991, the S Simpson name was dropped and DAKS became the new brand name.^[5]

The ease-of-wear of the trousers and how they allowed movement, as intended from Simpson's invention, led to DAKS being popular in sporting wear: kitting tennis, golf, motor racing and football players, and even for the British Olympic team in 1960.^[2] The company was commissioned by the British Government at the time of the Second World War to produce military uniforms for officers in the Army, Navy, Royal Air Force and Women's Services.^[6] Despite the semi-destruction of the Stoke Newington factory due to bomb damage and loss of electricity^[3]: 54 seven million garments were made for the military.^[3]: 58

After the war, DAKS started selling to the public again. Queues of people would form along Piccadilly. Simpson tailors would measure them in the line, and present suitable pairs of trousers to them when they arrived in the Simpsons of Piccadilly store.^[3]: 58

Simeon Simpson's son Alexander Simpson founded Simpsons of Piccadilly.^[3] The new building was designed by architect Joseph Emberton as a new and revolutionary retail establishment,^[3]: 28 the shop front windows exhibited the first curved glass display in Great Britain and the largest in the world at the time,^[3]: 17 these were designed so that no reflection would be cast to obscure the displays inside. The store opened in April 1936 by Sir Malcolm Campbell, the world-famous motor-racing driver.^[3]: 25 and was known for its visual merchandising and window displays by László Moholy-Nagy, a former director from the Bauhaus school.^[7] Alexander Simpson died the following year of leukaemia aged just 34.^[3]: 37

Simpsons continued to trade in the Simpsons Piccadilly building for several decades more, helping officers and civilians during World War II,^[3]: 53 and in later years branched out to sell other clothing by designer labels such as Armani and Christian Dior^{[3]: 123–124} Since 1999 Simpsons stopped trading at the Piccadilly store and moved the renamed DAKS to a new flagship store and London offices on Old Bond Street,^[8] whilst moving to another new store on Jermyn Street which was refurbished in 2012 to focus on selling classic menswear.^[9] The original store was sold to bookseller Waterstone's and is now their flagship store.^[10]
