I have this HC that GT clothes are actually are in some sense, part of body. They regenerate with you, not only restore when you ressurect. Like, you can even move a cape after some practice with your will alone. Like, some Maids do the spiderman or Attack on Titan thing but with leg bandages. Or Thiefs who snatch goodies with those long... what even are those. It gets a bit weird since you can take those clothes off. And give someone else...

And Alchemize them too. Dave mentions they’re magic and self-cleaning, and with the God Tier resurrection I’m rather sure they’re self-repairing as well indeed, but I don’t know if I’d call them an extension of one’s body. Instead I’d imagine them as a very easy to manipulate tool if anything? Like- Aizawa’s scarf thing in BnHA.
