I used* to do Gap’s stretchy crew neck because it was fitted and you could get away with a smaller size and not have the hem in your midriff. Gap’s stock is all over the place atm, for obvious reasons, so no idea if they have any.
I’m a fan of Gildan - cheap as chips, not cut like a sack and plenty of colours. I use them for smart-ish when they’re new then work/exercise as they get a bit of wear. Best I’ve found so far.
Any suggestions for medium weight cotton t shirts that aren't cut like a sack?
