Sounds like a plan getting rid of polyester. I fetched a little jacket with me here and I wore it yesterday evening but the sleeve lining is poly and after a very short while I was running with sweat, so that will be looked at to see if I can alter or else it's going.
I have a lot of clothes again after a boring period of lockdown with nothing much to do apart from sew. I try to work on a one in one out policy but it has gotten away from me big time recently so some serious pruning will happen soon. I am also rapidly coming to the conclusion that I really don't enjoy sewing for me and I do enjoy clothes shopping. Yesterday I bought a pair of trousers and a great shirt in no time at all. No fabric hunting, pattern adjusting, sewing unpicking sewing unpicking. Quite a nice experience instead
My normal sorting out policy is anything that doesn't fit etc goes, then I sort by sets - each thing has to work with at least 2 other things - orphans not allowed, mind you I've done that for years so no real room for pruning there, but it might give you a start point.
