Polo Ralph Lauren Large Sport Shirt I bought this over a year ago from a fellow SF'er (don't recall who) but the sleeves are too short for me. It's a fantastic shirt - you won't believe this because it's a regular blue label, but the cotton has that 10-year old, broken-in, super soft feel. It isn't sheer, but it's so lightweight and breathable that it's perfect for summer. I wish I had a dozen shirts in this same fabric, it is that nice. Tagged a Medium, measurements are 21" shoulder, 22" pit-to-pit , 24" sleeve.
