Nice looking shirt
Size: Large, Color: Black
A very nice shirt. Bought it for a “polka dot” dance so needed a polka dot shirt. But, it’s nice enough to wear for going out or golf. Yes, the inside is white but it’s not distracting. The medium was just right. Sometimes wear a large.

Little cheap shirt
Size: 3X-Large, Color: Black
Very cheaply made, definitely not the correct length and absolutely not for tall people. I took the hit and donated the shirt to a homeless person because it's not worth the hassle of trying to return it.
