This knee-length afternoon coat, designed by Jeanne Lanvin, is made of black silk chiffon, to which squares of black wool crepe have been applied arranged in a radial pattern from the yoke, increasing in size towards the hem. The binding cuffs and double band collar are of the same material. The coat is cut with a slight flare from shoulder to hem and there is no fastening. The sleeves are long, slightly full and tapering to the wrist.

This coat is a significant example of the meeting between fashion and modernity: the geometrical forms, assembled according to the 'collage' technique, refer to the strong influence of abstract art on fashion during the 1920s. Black became an increasingly fashionable colour for elegant evening wear and was popularised by Coco Chanel in the mid-1920s.
