Although "A Million British Pounds" is only a novel, if there really were a poor boy who transformed overnight into a millionaire, and if he asked a genuine old Londoner for help on how to dress like a true gentleman of high society...

Constructed in 1811, Regent Street was built by order of George IV during his regency, and though he had numerous faults, it must be acknowledged that during his time as Regent and King, he played a crucial role in the development of commercial streets throughout West London.
