Beautiful Shirt
Color: Rose, Size: XX-Large
I love the quality, looks,and style I buy them for my husband. They wash well the only thing I don't know is how they dry in a dryer because, I hang his to dry but one thing for sure is that I don't need to iron them because they're not wrinkled and for me that's a win. I highly recommend them. One thing not all styles are true to size. I've bought 8 other styles the COOFANDY BRAND in XL they fit and hang beautiful but in this particular style, I had to get him XXL. My husband is 5'10 and 200lbs
