Good Fit but too long
Size: Medium, Color: Army Green
I would give these shirts a 5 star rating if they weren’t so long over the waist, even a medium sized it doesn’t matter way too long

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.

Got these for my husi. He was very pleased with the look and feel of it. Danced all night at his sister’s wedding. These bad boys were perfect with his sage coloured suit! He is an 8 1/2 and we got his exact size Fit perfectly with no complaints. Material is really strong too and the price was the best overall.
