Clara was the ideal flapper, with short bobby hair, short skirt, and small breasts, she came to define the 1920's and everything that it represented. Keep in mind that alcohol was banned this decade. No alcohol = men find small breasted women sexy? Discuss amongst yourselves.
Clara made the movie "It", which coined the term "the it girl". Fancy. The reason it was called "It" though is because its original title "SEX" would never have made it through the sensors. Critics of the day said "this movie doesn't have 'it', it has 'those'". 'Those' meaning her breasts for those of you too slow to keep up.

Clara's career wound down quickly with the advent of talkies, as her thick Brooklyn accent put off viewers - she was the Fran Drescher of her day.
