Answer:
Their new social, economic, and intellectual freedoms.
Explanation:
During the 1920s, female fashion experienced a transformation. Fashion began to move away from traditional ideas of femininity, and instead embraced ideas that were considered more "masculine" and rebellious, such as slender bodies, lack of curves, short hair, short dresses and makeup. These trends were not only popular for aesthetic reasons, but also because many women considered them to represent their new social, economic and intellectual freedoms.
