Warren and David Gold helped make London synonymous with style when they opened their shop Lord John in Carnaby Street in 1963, attracting the Beatles and the Small Faces among others.
Now their contribution to fashion has been marked with a plaque unveiled by Robert Davis, the deputy leader of Westminster Council, in the presence of Lauren, daughter of the late Warren Gold.
The style icon brothers died in 2009 and 2015 having dressed the Rolling Stone, the Kinks and others at the epicentre of London's swinging sixties.
Ms Gold said the plaque was "a huge honour and deserved tribute to some of the most inspiring and legendary men to come out of the 1960s".
Mr Davis added: "The Gold Brothers played a massive part in creating the sartorial spirit of the 60s.
"The Lord John shop made Carnaby Street the outfitter of choice for the era, whether it was clothing the Rolling Stones or moulding the sharp look of bands like the Small Faces and the Kinks.
"The top acts of the day knew the Gold Brothers’ style was an essential part of their success. Lord John put music fashion on the map, and it is absolutely right that the store stays on the contemporary map of London with its own plaque.”
