Bias Cut

During the 1920s, women's dresses were starting to be cut on the bias which made them drape and flow nicely. This was primarily introduced by Madeleine Vionnet. Also, this fashion was greatly introduced by the cubists.

Cubism

Cubism was an avant-garde art movement. The art movement consisted of objects that were broken up, analysed and andre-assembled in an abstract form. 

This influenced fashion, garments sleeves were often long and full, bodices bloused loosely over lowered waistlines. 

Scarves were often slung across the shoulders and sometimes tassels and fringing hung from sleeves and hemlines.
