Why did the female leads in movies and TV series wear so little, while the men were very formal?

This problem involved factors such as costume design, character setting, and audience groups for movies and TV series. Costume design for movies and TV series was usually based on the identity, personality, and setting of the character. In some movies, female characters may wear skimpy clothes to show off their figure and personality, but also to create a romantic, lively or relaxed atmosphere. In other movies, male characters may wear formal or formal clothing to show their professional or social status. In addition, the audience of movies and TV series would also affect fashion design. In some audience groups, women were more concerned about the coolness and sexiness of clothing, while men were more concerned about the sense of professionalism and formality. Therefore, the female characters in the movie might wear clothes that better met the needs of the audience. The costume design and character setting in movies and TV series took into account many factors. Different characters and audience groups had different needs and preferences, which would also affect the design of the costume design.
