I lost weight and dropped from a Large to a 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 is from my personal collection. The shirt is 100% cotton. My cotton shirts are laundered at an organic cleaner. I do not wash and heat dry them. The colors are still strong, imo. The blue is slightly more royal than nave and the pony is a bright more goldish yellow. It will need a pressing when it gets to you. I have a busy law practice so please forgive any delays in responding to questions or shipping items out.
