I'm still learning about what clothes are bad.
I'm really annoyed that my favorite underwear might not be the best. It's hard to find stuff that fits. I'm built wide (legitimately big boned, and I'm also fat) and even when I was at my fittest, clothing was hard to find since I'm built more like a linebacker from American football than anything else. Wide hips and a trim waste is more normal for women, but not for guys.
Anyway, enough complaining. I'll eventually find underwear that is decently priced, healthy, and deals well with sweat (very necessary since no one likes swampy bits, and there are days when I sweat at work even in the depths of winter.
