I'm about 5'9"/145, and I bought a medium. This is pretty much just your standard crew neck T-shirt, though the neck is not as constricting as it is on cheaper crew neck tees. The cut is slightly slimmer than on other medium-sized shirts I own which seems to be a pretty standard thing for BLK DNM. But if you're on the slimmer side, I think you'll like the fit. What sets this tee apart from others I own is it's really smooth, almost silken, feel.
