A T-shirt chic? YES!!
Size: X-Large, Color: Wine Red
This is the second one of these shirts I’ve ordered. I don’t wear ties anymore, so I actually wear this mock turtle neck under a blazer, or a sports coat as my father used to call them. I wore a blue one the other evening and I wore it underneath a plaid blazer. Whoever would guess a T-shirt could be quite so chic. It stretches plenty, it’s light and it’s so comfortable. I have two of them now and I’m deciding on a third one.

Gals can wear this too!
Color: 2 Pack(black+white), Size: XX-Large
Do you know how difficult it is to find a cotton mock turtleneck??? This review is NOT for guys but for gals. Being in menopause my temps are all over the place-- one minute I'm hot then I'm freezing. I needed a short sleeve (plus size) cotton mock turtleneck to wear under a cardigan. I'm so pleased with this shirt... the fabric is soft, NOT see-through, it's breathable since its primarily cotton (95%), it's not super tight, and it's comfortable. Hopefully the info will help other gals looking for similar shirts.
