Made a different comment. Deleted it. Had a better idea:
Those loose, light clothes that people in middle-eastern cultures still wear as traditional clothing. There is a reason they came up with those when they did. Elsewhere in this thread another peep was complaining that men don't get to show enough skin and specifically citing heat as the reason this annoyed them. I say fool. Showing skin will not save you from the heat, especially as climate change continues to cook the planet. It will, in fact, make it worse.
If we are to survive being cooked alive by the sun, we will need to cover up, as the people who inhabited arid-and-extremely-hot places for centuries have done.
Actually, since the Dune series got an injection of popularity with non sci-fi nerds thanks to the Denis Villeneuve films --
-- We could call it "Fremencore". Integrate some futuristic aesthetic influences so people don't think it's cultural appropriation.
I do believe there is a niche of people into that. Though my view might be skewed by The Algorithm :tm: knowing I like vintage fashion.
My youtube shorts recs are full of chicks trying on their grandmother's old and well-kept clothes from the 50s~70s.
