After WW1 women wanted more practical clothes, more freedom of movement. Women over the age of 30 had gained the right to vote in 1918 (about time I say). There was a mood in the air of recklessness, after the war people felt they could die tomorrow so lets live for today. Women had worked during the war doing so called men's work, women had had to wear clothes that were practical for this purpose. The twenties were highly liberating for women, popular sports included tennis and swimming. Sportswear was born with Chanel at the front of it all with her short hair and practical clothes.
