Brooks Brothers fits slightly large. Stick to your usual size but pick the fit name carefully — Madison/Traditional is very full, so most modern dressers do better in Regent or Milano, and many size down one in knits and polos. Shoppers generally find Brooks Brothers cut on the generous, classic-American side, with the fit label (Traditional/Madison, Regent, Milano, Soho) mattering far more than the numeric size.
