I don't really care too much about having a top end rich ppl tailor I thought high end brands like the oneI mean personally, having bought many leather jackets and essentially lost money on the whole thing as we all have, if I were to go out aiming to spend $4k on a jacket, I would just get my ass over to one of the top tailors in London (or depending on style preferences, another city or shop) to get some kind of wool (whether tweed or something else) jacket made and just live in the thing. It'll hold up to it too (old fashioned people like King Charles wear their outerwear until the lining is shredded, then get it relined and wear it for another few decades).
