Woman in German hussar uniform, 1916.
From the marking on the back of this picture postcard, this is a wartime photo although the woman wears a full-color peacetime hussar uniform. The photographer's location is Niederbronn in Alsace (now in France). The German hussar regiment garrisoned in that region was the 2. Rheinisches Husaren-Regiment Nr. 9, but I do not know if this is that regiment's uniform.
