Typically, I’ve not got around to actually doing this… Pitty, I know! But perhaps for now you could just wear one of your old t-shirts. Only you could do it in the materialist spirit: confident that no perfect t-shirt exists in the ideal realm of platonic forms, of which your own garment is meant to be a mere sketchy approximation. No indeed, your good old t-shirt is as perfect as t-shirts get, provided you have not stained it like I have mine, by eating like a pig.
