Vintage BROOKS BROTHERS ESTABLISHED 1818 Brooks Brothers Navy Solid Sweatshirt Size is L, but it's not that big, feels like S to M. Please refer to the size measurements in the photos of the actual item. This is from about 20 years ago. It was an expensive gift for me at the time, so I kept it and couldn't throw it away. Used, with signs of wear and stains, but it has a nice, worn-in feel. Brooks Brothers is the oldest clothing brand in America, founded in 1818. It has been loved by successive American presidents (Lincoln, Kennedy, etc.) and celebrities (Fred Astaire, Andy Warhol, etc.). Brooks Brothers' basic philosophy is "to make and handle only the highest quality products. To sell at prices that include only a fair profit, and to deal only with customers who understand its value." Under this philosophy, they have pursued the American classic style for over 200 years.
