Merc London was established on Carnaby Street in 1967 when London was in full swing. Merc London Clothing epitomises the look of the 1960s mod and skinhead. Merc London is one of the finest names in British fashion; retro style, a rich heritage yet still looking ahead, but always with the Mod and Skinhead scene at its core.
