This Asian inspired coat is a very early example of the direction that Bonnie Cashin would explore in the decades to come: simple "T" shaped coat with narrow mandarin collar. Here she uses linen and embellishes it with frog closures in a design for Adler and Adler. Later those frogs would become her signature brass twist locks.
description from "Vogue", June, 1950:
"Sawed-off Chinese coolie coat--new length: white Irish linen, frog closings: three-quarter length sleeves. A summer coat with more than one life to share. First and foremost, a life with a bathing suit; then, perhaps, over a slender skirt in town, slacks at home. Coat by Bonnie Cashin, $30, At Lord & Taylor; Garfinckel's; Neiman-Marcus."
This photo of Bonnie Cashin shows her wearing the same coat, worn casually with pushed up sleeves (a style she favored).
