I like the shirt and the price was decent
Size: X-Large, Color: Black
Nice but I don’t like it on my neck. I’m giving it away as a gift.

Too small for the shown size.
Size: XX-Large, Color: Black, Size: XX-Large, Color: Black
I usually would buy XL size but in this case I bought XXL thinking since it's cotton it might shrink. But when I tried the T-shirt it was too small. My older XL sized T-shirt has 2 1/2" larger total shoulder width and 3" wider body width. See attached pictures. Length was also a bit shorter by about 1/2". I will to return it.

Super soft, runs small, long tail
High quality, super soft, good neck height, nice price, ready to go right out of the dryer, medium thick material, works well under a sport coat or sweat shirt, snug fit--runs about one size small. Length is about four inches too long. So, ideally made for tall and skinny people (I am short and thick), but going one size up works fine for me except have to tuck it in due to the length.
