Sales have started at Office, Sole Trader and other British retail shops for the first Gibson London footwear collection, developed by Base London under a long-term licensing deal with the British brand of men’s suits by the same name, made famous in the 1950s and ’60s by its dandy styles. Base London, which had a stand at the last Micam show, is developing its export business, but its Gibson London line will be offered for the moment only in the U.K. and Ireland.
