Great shirt but won’t work if your slim cut.
Size: Large, Color: Dull Pink
Fabric is nice and looks of good quality, just is a bit wide in the torso, so it doesn’t fit my slim fit husband. If you wear slim fit dress shirts I would likely say this shirt will be boxy on you in the waste. Good price if it works for you and comes in so many color options!

No negatives about these shirts.
Size: XX-Large, Color: Light Green
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.

Excellent shirt for thr price. Generous in size. Washed in warm water dried on high heat and it is perfect. IMHO it does need a light press. I bought 3 in size XXXL.

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.
