Hi, and welcome! I'm from a small European country too (Естонија) Your English is really good, actually, definitely no need to apologise for it!
I can relate to your situation, I was unemployed back when I found YLF, so without much money for clothes as well. I do have a decent job and income now, but I still prefer to have fewer clothes that I love and wear all the time.
Would learning to sew some of your clothes yourself be an option? I've tried to do that myself, but I'm pretty bad, nay, horrible at it And if fabric is expensive, then this might not even be cost-effective anyway.
