Fiancé Approved
Color: Royal Blue, Size: Medium
Perfect for my fiancé's new job. He said it's fit is true to size and it is more comfortable than the one he got at a store in the mall.

Order a size larger than usual.
Color: Light Blue, Size: X-Large
They tend to run small. My husband usually wears a large and I ordered an extra large and was glad I did!! They wash and dry beautifully!!

Very wrinkle free and sheds off liquids well.
Color: White, Size: X-Large
Very very nice shift. I’m usually XL and that’s what size I purchased and it fits perfectly.
I recently purchased one for my sons 5th grade graduation and the fit and feel was better than the 80.00 and 89.00 shirts I purchased for him at Dillard's, which were
returned.

Great shirt!
Color: White, Size: X-Large
This shirt is all that! It's beautiful and feels soft yet very stable fabric. White is always somewhat see through but this one isn't bad, unless you wore black under it.
My husband loves it!
