 Tailors , attracted by the affluent and influential nature of the residents of Savile Row , started to open businesses in the area in the late 18th century , first in Cork Street , about 1790 , then by 1803 in Savile Row itself . None of those original tailors survive today , though Henry Poole & Co , who through Edward VII 's patronage , helped make the street fashionable , still have a presence in Savile Row . Poole moved the company into 32 Savile Row in 1846 , following the death of his father James Poole , and the company is now at No. 15 . Henry Poole is credited as creator of the dinner jacket , when he made a smoking jacket for the young Edward VII in 1860 .
