Proenza Schouler takes an abstract approach to Autumn/Winter 15, drawing on the work of Helen Frankenthaler, a New York abstract impressionst, in particular. While Frankenthaler's palette may not necessarily be reflected in the Lazaro Hernandez and Jack McCollough designed collection, the spirit of expressionism is in there: "She was just this really inspiring character for us, the whole idea of expressionism and spontaneity...this rawness to creating." said Hernandez. 

The rawness is expresses through slashed fabrics, a theme that pervades the collection, from tops and dresses and coats alike. A cut-out motif, sometimes exposes bare skin and sometimes is layered over another fabric to create a textured look. Skirt edges were intentionally slashed and frayed and injected a spontaneous sense of movement to the collection. 

Cowhide fabric and prints stood out as a bold accent, making up both a coat and a dress. Shoulders were on show as necklines cut a straight horizontal line across the chest and around the arms, leaving much décolletage on display.
