Shirt the most classic of Borg Polos a wimbledon winner. I have two of these, one with red detail and one with green. Lightly worn, SIZE: The chest size in pit to pit allows for the elastine stretch and the uk chest measure is accurate. Small = UK 36" Chest (19-21" pit to pit), USA 38. Some people do go up a size preferring to wear loose Selling each for $30 or both for $50.
