Is trendyol fast fashion?

I know this is formatted weird but this has been bugging me for awhile, I've never been someone who throws out clothes or buys them unnesicarily. I wait at least 2 months to buy something and I make sure I can match it with what I already have. That was because I didn't want to be a part of the shein gurus who just follow trends and don't consider unethical labour. And when I heard turkey has very strict rules with manufacturing, and pay fair wages, I started buying from trendyol; especially because you can even ask in the q/a section where their shirt is manufactured . Anyway, I've been finding a lot of conflicting info abt this. People are saying that their manufacturing includes no unethical labor and that they have very strict laws. but I also have been learning about Turkmenistanian labour ( which includes cotton labour) and how turkey is apart of it. Their site also screams fast fashion... Like just look at it and you can tell. But also from looking at it you can tell that they also host alot of independent business which I think is cool, the quality of clothes is good and the prices aren't cheap, which leads me to think that they don't do slave labour. Because I continued to buy from them regardless I have started to feel quite shamefull and guilty, not only because I stpped buying from shein but went right back to another fast fashion brand, but mostly because even though there is a possibility of it being slave labour, I continue to want to buy from there. What I'm asking for is some advice on this, specifically the slave labour part since I don't throw out clothes and don't compulsively buy, and insight on whether trendyol is actually uses slave labour .
