An aspiring writer asks: “What type of clothing do you think would be found in the distant future, around the 23rd century?”
Virtually anything is possible that far in the future. The clothing question is dependent on the conditions that an author sets for the story. Are people constrained by wealth or technology? In other words, how wealthy is the society, and what technologies does it have available? What are the society’s values and desires? If present trends continued, the planet would be immensely wealthy and technologically advanced, but that is for an author to decide.
One could imagine anything from people wearing natural materials because that is what they prefer, to nanotechnology-based “fields” that perform every function of clothing and more.
