Is this even Story and Lore related?
Yes, as the current hat situation sort of violates lore. and common sense. Most of the other races can, in theory, get by with the hats that are in game (though zabraks would find them uncomfortable). Twi'leks though are forced to deal with hats that do not fit their head shape (causing clipping in game and would, in real life [were they real], simply not fit them).
