Just hear to echo that Hanes beefy are comical.
Carhartt pocket t’s are the go to (regular ones never tried WIP), one size down, but needs to be like your actual size imo. For reference I am short, 5’7” 170, wear a small (instead of a medium), when I’m dressing like an old adult, wearing reasonably fitting 501s. If I’m out skating in 874s, I’m probably wearing a medium. I like these shirts because I have a proportionally longer torso, and so T’s can quickly start looking early 2000s short t, baggy pants. And I am painfully aware that some young people make this look very cool, alas, not so much on a list middle aged out of shape person.
Dickies last way longer than I thought, but I have a hard time finding what is what because I swear they have different levels of the same product. Kind of like how Levi’s sells obviously shittier 501s to old box stores. Labeled the same, but lesser quality. So usage may vary, but dickies pocket t’s have been mostly pretty decent.
