Best budget yoga pants?

Now that I’ve become an instructor, I need some fresh attire because my favorite pairs are getting worn out. (My best ones have been hand-me-downs, and of course expensive brands.) I’ve seen a lot of recommendations for brands that cost 80-100 bucks per pair and I just can’t afford that right now. Has anyone had luck with Amazon, etc? I prefer flared, but don’t mind either way. I’m mostly concerned about cheaper pairs being see-thru.

Thanks!

Edit: I totally understand the issue with Shein, thank you everyone for bringing it to my attention!
