This is a lovely portrait of a woman in the 1930's with a typical bob hairstyle.
Her part is off center and she is bang-less. Her brunette hair has gentle finger waves with curls at the ends. The length hits at mid ear which makes this bob quite short. Her make-up is quite plain and she is probably not wearing any. Often the photographer would touch up the photos to smooth skin and refine details. She is wearing a blouse with flowers printed on it and two strands of pearls.
