When you think of hot weather you think of desert sands, right? What do the desert nomads wear and why? They wear loose, long, flowing clothing. Loose - to let in air, Long- to prevent sun and dust burn, and flowing-to circulate air. They wear turbans to absorb sweat and to prevent sun from burning their brains out. Yes, we think of taking off clothes, but those who live with heat and sun all the time think of putting loose, long, flowing clothes on!
