SEXY BLACK TURTLENECK SWEATER!
Size: X-Large, Color: Black
This is soft, looks amazing on my husband who is a big guy (6’2” @245) so not everything fits all the time. Sleeves are long enough, and the sweater looks great on him. Soft material, nice collar rate 10/10. Will try and get a nice pic of him in it!

Nice economy casual sweater,
Size: Large, Color: Off-white
The sweater is fine for the price, with correct fit. Arrived fast. Nice neutral cream/oatmeal color. It has a fairly loose open weave and is predominantly cotton, so it’s quite breathable and well suited for layering in cool but not truly cold weather. The knit is a little coarse, not really scratchy but not very soft. It’s a good value for what they charge. And fine for casual wear. But I ultimately decided to return it and spend a lot more to get a merino wool sweater because they are dressier, much warmer for weight, MUCH softer, and less bulky under a jacket. I like to wear mock turtlenecks under a sport coat in the fall and this sweater was a little too thick for that.

Soft and comfortable but runs a bit large
Size: Medium, Color: Off-white
I got this turtleneck in the off white color, and it looks very clean and easy to style. The color is true to what is shown and works well with casual or more dressed up outfits. The fabric feels soft and has a nice amount of stretch, which makes it comfortable to wear for longer periods without feeling stiff. The sweater feels lightweight but still warm enough for cooler days. It is not heavy or bulky, so it layers easily under jackets or coats. It also seems fairly wrinkle resistant. After wearing it and folding it, it still looked neat without needing much adjustment. In terms of fit, it does run a little big. I usually wear a medium, and while this one is still wearable, it feels slightly looser than expected, especially through the body. It is not a big deal, but I would probably order a smaller size next time for a more fitted look. The turtleneck itself sits comfortably around the neck and does not feel tight or irritating. Overall, it feels like a comfortable and easy to wear piece with good stretch, a nice lightweight feel, and a clean look. Just something to keep in mind on sizing if you prefer a closer fit.

Don’t recommend
Size: Medium, Color: Black
Got this as a last minute shirt for an event and it was roughly $12 on sale. The quality was ok, first wear was fine but it doesn’t hold up after washing and air drying. I don’t recommend unless only wearing once, there was a lot of shedding and pilling after the first wear. I’m rough 5 ft tall and about 140 lbs. and I got a M and it sat around my hips so unless your on the tall side this wouldn’t fit.
