La Rive Gauche (The Left Bank) is the left bank of the Seine River in Paris, as one faces downstream. Here the river flows roughly westwards, cutting the city into two: the Right Bank to the north and the Left Bank to the south.
More than simply a geographical region, the Left Bank has become a name for a particular lifestyle, fashion, or "look". In 1966 Yves Saint-Laurent launched a ready-to-wear line by the name Rive Gauche. The collection was an attempt to democratize fashion, introducing elements of garments of the lower classes into high fashion, such as the leather jacket.
