I've had some Hanes beefy that were cut differently where the sleeve joins the body but it was not that noticable. I've had Gildans too, same size and colour but they were both different shapes! I order some Jerzees a while back in medium and they were more like an extra small, I could only just squeeze into them and they were too short, looked like a crop top, which is not my style

, they must have had the wrong label.
I suppose it's expected when they make as many t-shirts as they do that some will be a bit off. The pockets are a different matter, they should have been picked up.
