Burberry Group plc is a British luxury fashion house, manufacturing clothing, fragrance, and fashion accessories. Its distinctive tartan pattern has become one of its most widely copied trademarks. Burberry is most famous for its iconic trench coat, which was invented by founder Thomas Burberry. The company has branded stores and franchises around the world, and also sells through concessions in third-party stores. Burberry was founded in 1856 when 21-year-old Thomas Burberry, a former draper's apprentice, opened his own store in Basingstoke, Hampshire, England.By 1870, the business had established itself by focusing on the development of outdoors attire. In 1880, Burberry introduced in his brand the gabardine, a hardwearing, water-resistant yet breathable fabric, in which the yarn is waterproofed before weaving. Burberry was the original name, but then the company soon switched to using the name Burberrys, after many customers from around the world began calling it Burberrys of London. This name is still visible on many older Burberry products. In 1891, Burberry opened a shop in the Haymarket, London, which still exists and until recently was the site of Burberry’s corporate headquarters. Now the headquarters are at Horseferry House just behind Houses of Parliament, Westminster (London).
