During the depression, a massive class difference opened up between the rich and poor.
The wealthy could still afford to keep servants, run their house and keep a weekend country retreat. They were still able to travel in luxury cars and shop in designer boutiques. The wealthy were well educated.
However, at the other end of the scale, a poor family of 8 or more would live in 2-3 rooms with no running water and no inside toilet.
During this time, fashion portrayed an elegant and sophisticated image. This was a reaction against the wild, daring youthful fashion of the 20s. Because of the financial hardship people often tried harder to appear well dressed and respectable.
The 30s was a quieter era, people were dressed and apprioately behaved in a respectable manner.
