Vintage long sleeve classic fit Ralph Lauren Polo

This shirt is a beautiful blue, at first I thought it must be denim to look so blue, luckily it’s 100% cotton. Since it’s a vintage shirt the XXL label shouldn’t be a concern, it seems to be the regular large to extra large size in men’s. I only just saw now while taking photos the red and blue striped designed throughout the shirt which I just love, gives it a unique pop without sacrificing subtlety!
