Clothes Reveal the Body. Corsets off! 

The First World War marks a break between the nineteenth century and modernity. A process of liberation becomes apparent, as huge numbers of women enter the labour market for the first time. The slim, elongated silhouette, with flat chest and hips concealed, gives women an androgynous image. The waistline moves down from just under the breasts to the hips. Modern dresses are suited to outdoor activities and dancing. 

Men's styles also adopt a slim, linear silhouette.
