Men's brown flannel button up shirt, warm and comfortable material!! XL

Purchased for my husband for Christmas and sadly it didn't fit him. Thus isn't the cheap, fuzzy flannel material, it is nice quality. I didn't notice when I bought it, but the bottom button is missing, as pictured in the 3rd photo. It would be a very easy fix. Please note that although we are a very clean household, I do smoke and have one lovely Calico cat who is beyond spoiled. :) Please feel free to ask any questions!
