During this time period women had a specific role which was staying home and taking care of the children, house, husband, etc. World War II brought a change to all of that. Women now played a very important role in the economy because they now had to go to work. They also received more pay.
In addition, the clothes that women generally wore changed. They usually wore dresses and skirts but they were now wearing pants, trousers, etc.
Women were given a new role to play and this really help to boost their self esteem and feel more important.
