> I’m more than happy to spend $30+ on a simple shirt that won’t change its fit after a few cleanings, but struggle to find a consistent brand.

Yes I face this problem as well. It seems that no matter how much you pay, you get the same clothes manufactured in the same sweatshops but you pay extra for a "better" logo/brand.

I like Zara, but it is debatable if they actually do have better quality for the higher prices they ask for.
