I love high necklines and wear both turtleneck and cowel plus mock neck. I'm blessed if I find a top with a nehru or mandarin collar.
On outerwear I look for stand up collars. I wear neck gaiters daily throughout winter.
Found this on "Ask a Stylist"/Stitchfix website.
A classic turtleneck has a more fitted neckline and hits one to two inches below the chin.

Wear a turtleneck if you have:
- A long neck
- A long face
- A short torso
- Narrow shoulders
The looser cowl neck sweater has a funnel neck and drapes to show off your neckline.

Wear a cowl neck if you have:
- A long neck
- Small or large bust
- A larger head in comparison to your upper body
- A larger bottom half
