Hello Henrik,
the young lady is wearing the dress as in use by the "Deutscher Frauen-Arbeitsdienst"
since about 1934. By the German population they were phrased as the "Amazonenkorps". It took until
the summer of 1935 as when the jacket as worn, became widely spread and worn.
In early 1933 smaller groups of girls from the BDM formed special sections, to enlarge female labor
service, pressed for by Lydia Gottschewski, a female leader for the BDM from the Reichsjugendführung.
In early 1934 the female labor service became a part from the "Nat. Soz. Arbeitsdienst". From April 1,
1936 the "Deutscher Frauen-Arbeitsdienst" was renamed and became the "Arbeitsdienst für weibliche Jugend".
