Nice shirt but to shiny for the office
Size: X-Large, Color: Blue
I really like the semi professional, clean, well groomed look of collar-less shirts for my semi formal office. It is appropriate for almost any office occasion. Whether we're getting a visit from the corporate execs., or going out for happy hour...I don't feel over dressed or under dressed.
However, for this item:
Pros:
1. Excellent classic fit
2. Good stitching and well made
Con:
It is to shiny! I truly want to purchase every color they have in their lineup, but because of the shimmer, this is probably for someone that wants a night on the town vs a corporate office setting.

Good quality
Size: Medium, Color: Black
I purchased two shirts for my husband and they were a perfect fit. The quality of the material was excellent. They recommend dry cleaning and I took them to the cleaners because they were wrinkled with the folds. We will have to wait until he wears one to comment further.

Great Quality
Color: Black, Size: Small
My son loves these shirts. We have them in several colors. They are so soft, light weight and wash great. He is in college and he can throw them in the washer and dryer and not have to dry clean them which is a plus for him. They are slim fit and hold up well. One he has had for 2 years and it still looks great. Great value for the money.
