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.

A nice, comfortable t-shirt with a bit higher moc neck
Size: Small, Color: White
I wear tee shirts a lot, but, because I need something a little warmer at times I wondered if such a thing as a moc-neck tee existed. This shirt is soft and comfortable, not tight but more tee shirt- like in fit.
