Favorite turtleneck
I'm a big guy- 5'6", about 385, and I ordered the 4x. It fits perfectly. I love the soft material and fabric, and it's slimming without being uncomfortable. The quality of the material is top notch, and I haven't noticed any piling yet. It also looks great with all of my dress and casual wear, with either khakis or slacks. I wear this under my overcoat for outside, and with a base layer underneath it for inside. Definitely a great value for the money.

Too thin, neck portion too hard to position to sport the classic turtleneck look.
Color: White, Size: Medium
Too thin. The neck won't hold a clean look, the neck portion bunches and double/triple folds and I can't get that cool turtleneck look with it that I had with my first white turtleneck that I loved so much I wore it out. This one doesn't measure up. If you just want this kind of shirt to wear in warm weather it's good for that because it's very thin.
