Seeing as you are somehow able to utterly evade a huge ass explosion 40 feet in diameter without taking a step to the side, and you are fireproof, you really shouldn't worry too much. And every time we meet someone you kill them and loot their bodies before they can utter two words, so your clothing expenses are well covered.
Btw. have you noticed how you are the only character losing all her clothes as a matter of habit?
