Which 1965 Yves Saint Laurent collection was inspired by Piet Mondrian paintings?

Yves Saint Laurent's 1965 Mondrian Collection was inspired by Piet Mondrian's paintings.

Saint Laurent's fall 1965 haute couture collection paid homage to several modern artists, but Mondrian's influence became its defining association. Six especially famous cocktail dresses used black geometric lines and blocks of white, red, blue, and yellow to evoke the Dutch painter's abstract compositions and the visual language of De Stijl.

The dresses were more technically demanding than their simple appearance suggested. They were assembled from pre-dyed pieces of wool jersey and silk, with the color divisions integrated into the seams rather than printed onto one continuous fabric. The construction helped the A-line dresses hang cleanly without distorting the geometric pattern.

The collection became a landmark in the relationship between art and fashion. One dress appeared on a 1965 Vogue cover, and inexpensive copies soon spread the look beyond haute couture. The name can cause confusion because “Mondrian dress” may refer to an individual garment, while “Mondrian Collection” identifies Saint Laurent's wider 1965 collection.
