They often wore their hair short, with beaded necklaces or earrings, and a loose dress.
The prohibition made purchase and consumption of alcohol illegal. It was considered a moral triumph for the middle class. It made little to no difference to the wealthy, as they could just buy anything. This also gave rise to the gang-era.

Organized crimes were growing rapidly due to the prohibition, mostly in major cities like Chicago and New York. There were many forms from gambling, to drug trafficking, and many more. Later in the 20th century, the government used anti-racketeer laws to convict members of the mafia, but it still is in business to this day.
The roaring 20's was also called the jazz era because of new type of music that was emerging. It was a new style that came out of nowhere and was smooth and "romantic". There were many artists during this time period, such as Louis Armstrong.
F. Scott Fitzgerald became well known as one of the main speakers for the Jazz Era, people felt that he "spoke to their generation." He was born in St. Paul, MN and attended Princeton University. He served in the army from 1917-19, then met and married Zelda Sayre. They were considered each others "worst enemies." They were often unfaithful, and became alcoholics.
For the first time ever, Americans lived on more than just farms, they lived in big cities. The nation almost doubled in their wealth, and it brought on a consumer society. The lifestyle was wild, parties, new music, dancing, and using slang.
