A correct prediction of Wikipedia's "200 1 Space Roaming" is that people's clothing will not change much in 200 1 year. Recently, science fiction movies have long stopped people from wearing that kind of tights, and the costumes of people in Avatar are the same as today.
I have to say that the shiny tights used to be for the visual effect at that time, but now there are more schemes in science fiction films, such as a large number of generous aristocratic costumes in the prequel trilogy. Even if it doesn't conform to today's clothes, it's just a difference in design, or people's clothes are tight enough today.
In historical films, there are basically a lot of aristocratic loose clothes. Because no matter at home or abroad, nobles should show their elegant demeanor without labor and farming, so they can wear loose clothes. Soldiers, servants, ordinary people and tenant farmers must wear close-fitting or even tight clothes to avoid being entangled in weapons or farm tools (this is what China used to say in ancient times); Second, according to the hierarchical system of feudal society, many clothes with wide robes and big sleeves were not for them.
The tights in science fiction films are mostly to create a sense of the future times (because from history to the present, everyday clothes are generally developing in the practical direction and getting closer and closer); The second is to show the graceful figure of actors and stars through tights to attract the audience.
