I’ve got 11 of them now so it’s safe to say these are the best long sleeve t-shirts I’ve ever had. I wear them almost every day. They are so soft, very flattering, warm and the perfect length. And I love the length of the sleeves! I live in a colder climate so in winter I wear them as a base layer underneath a sweater. The softness of these is incomparable. I’m a size 8 on top and I usually get these in a size S which is perfect. I’ve got some in a size M as well, they fit too but I’ve noticed that they do stretch out a little if you wear and wash them often. If you want them snug, get a smaller size. If you like them a bit loose, get a bigger size. If only they were cheaper, I’d have 100 of them.
