Chemise - It is an undergarment worn by women. They were now much shorter and more narrow, following the silhouette of women’s dresses. This particular one is made of blue silk "crêpe de Chine" with lace insertion.
Windswept Bob - extreme hair! Personally I find it hard to distinguish whether the sitter had a rough journey to the photographers or has overdone the "Windswept" part of the look. Perhaps it serves to prove that an attractive face can get away with anything. This style was very popular at the time and has a place in hairstyle history.
