RED, RED WHINE?: Giancarlo Giammetti, the longtime business partner of designer Valentino Garavani, has been watching with some bemusement the polemic over red soles ignited by Christian Louboutin’s legal action in New York against Yves Saint Laurent, alleging infringement on its trademark color. Giammetti points out that the now-retired Roman couturier, famous for his red gowns, also designed shoes with red soles way back in 1969 and 1983. In the latter year, Garavani also made soles in rhinestones and in fabrics to match the clothes. Louboutin started using red soles in 1992.
