According to the article Girls need pockets, how did World War II affect women's clothing? Many women wore more form-fitting clothing during the war because the government said it helped to boost morale for men fighting.

Because many women worked in manufacturing during the war, it became more common for them to wear clothes with large pockets.

Due to the limited availability of clothing fabrics and textiles during the war, women's clothes became simpler and had fewer pockets.

During the war, many women started wearing overalls so that they could get hired to work in factory jobs left vacant by men who had left to fight.
