"Mondrian" day dress, autumn 1965
Yves Saint Laurent (French, born Algeria, 1936)
Wool jersey in color blocks of white, red, blue, black, and yellow
As the sack dress evolved in the 1960s into the modified form of the shift, Saint Laurent realized that the planarity of the dress was an ideal field for color blocks. Knowing the flat planes of the 1960s canvases achieved by contemporary artists in the lineage of Mondrian, Saint Laurent made the historical case for the artistic sensibility of his time. Yet he also demonstrated a feat of dressmaking, setting in each block of jersey, piecing in order to create the semblance of the Mondrian order and to accommodate the body imperceptibly by hiding all the shaping in the grid of seams.
