"The Flappers' image consisted of drastic - to some, shocking - changes in women's clothing and hair. Nearly every article of clothing was trimmed down and lightened in order to make movement easier. The new, energetic dances of the Jazz Age, required women to be able to move freely, something the "ironsides" didn't allow. Replacing the pantaloons and corsets were underwear called "step-ins." The outer clothing of flappers is even still extremely identifiable. This look, called "garconne" ("little boy"), was instigated by Coco Chanel. To look more like a boy, women tightly wound their chest with strips of cloth in order to flatten it. The waists of flapper clothes were dropped to the hipline and they wore stockings. Authors such as F. Scott Fitzgerald used the term to the U.S., half reflecting and half creating the image and style of the flapper. Fitzgerald described the ideal flapper as "lovely, expensive, and about nineteen." In the book the Great Gatsby as well as the movie all the girls are dressed and act like flappers.
