Can't say enough good things about these shirts. I have purchased several colors of these shirts and they fit wonderfully. I have a belly so button down shirts that actually fit are hard to find. They are either too big across the shoulders to fit my belly or just too tight around my belly. These fit and look create and i will buy them again as needed.

Sizes Run Small

Size: X-Large, Color: Classic Blue

Love the fabric & colors. Amazon delivered on time. But, be aware, the sizes run SMALL. I have 15 year old size large dress shirts that I bought at Kohl's that fit perfectly but are showing their age. I tried a size large in these & they are too small. An XL fits perfectly.
