I have a lot of bad luck with t-shirts' necks stretching and distorting on the bottom (unevenness). I always take good care of them and do not stretch necks when putting on hangers. The only thing I can think of that is causing the damage is that I hang them immediately after taking out of washer, then let dry, then fluff in dryer.
I have had the most problems with Hanes that you pick up in packs at Walmart, etc. I have a couple pairs of Anvil that I like and haven't had problems with. I also have a couple Hanes Beefy-T's that I like but haven't had any problems with, but they aren't worn much since they're one size too large.
I am looking for recommendations for good quality (I realize this is relative) t-shirts that aren't too expensive (preferably under $7 each ).
