Sizing: Ron Bennett - Ties
"The Ron Bennett brand comes in a variety of fittings. Polo shirts are a relaxed fit. Non-iron business shirts also come in a relaxed fit with a longer body and sleeve length (96-97cm instead of 92-93cm). So you may want to choose a size smaller than normal. Sports or casual collared shirts come in a classic fit, so should fit true to size. To be sure of the correct fit, please refer to the guidelines below."
