James Poole first opened a linen drapers in London in 1806. By the time of the Battle of Waterloo, Poole had set up as a military tailor, opening an emporium at 181 Regent Street - later moved to 4 Old Burlington Street. Upon James Poole’s death in 1846, his son Henry enlarged these premises and built a palatial showroom with a new entrance opening onto the adjoining street of Savile Row, thus inaugurating the long tradition of the Savile Row suit.

from CHURCHILL STYLE
Churchill was always drawn to fine clothes. Having bought breeches as a young man, and his first military uniforms as a young cadet, he next added frock coats, trousers, and vests, as part of his new Parliamentary wardrobe. His suits and overcoats were often made by Henry Poole. As early as 1905, Churchill visited Henry Poole’s original Savile Row shopfront and returned often. In later years, a cutter was usually dispatched by Poole’s to measure Churchill at Chartwell.
