I will note that the Ala Mighans are also guilty of wearing gear that is extremely ill-suited to the desert.
You always cover your back, neck, and shoulders with light, light-colored fabric if you don't want to get sunburn. The rest of you could be naked for all I care, but the parts that are exposed most to the sun have to be covered. It's clear, however, that FFXIV's world simply doesn't care for this rule, in the same way you can run around in your bikini in Coerthas and your PC doesn't so much as shiver from the exposure.
So you know, yeah. Realism. Doesn't really work here, at least in this case.
