Aghhggh I have the same issue, I'm perma-uncomfortable. for a while, like 15+ years ago I had jeans custom made for me and it was bliss, but custom clothes are just not really feasible for me now. Tops are also a struggle so.. I would have to investigate if I can use the platform you mention in my country (orrr learn how to sew but I know that 'aint gonna happen).
