I lost weight and dropped from a Large to Medium. I have a huge collection of Ralph Lauren items in Large that I will be posting over time, as well as a large number of Medium items that were meant as replacement items but didn't work out for whatever reason. This shirt has that classic plaid look to it and is very good looking, but I think this was part of the "Big Shirt" collections which weren't always marked as such. Those shirts were much roomier than the Polo classic fit. I've included pit to pit measurements but this is a fuller shirt in comparison to the Classic Fit from Polo. The shirt is in great shape. It's just too big for me. I have a busy law practice so please forgive any delays in responding or shipping. Thanks.
