Nice fabric.
Color: Red Gingham, Size: Large
This was a well made shirt and the fabric was nice. However, I had to return the shirt because it was too small. I read the reviews which said it ran large. So, I ordered down a size, should not have done that. I believe it is true to size, but I’d not a fitter or modern cut.
