Great question! Our shirts are sized only by your neck measurement because the sleeve lengths are standardized. We have a modern and a slim fit in our shirts just like our suiting. If you typically carry more weight in your waist, the modern fit shirt will be great for you. If you have a leaner upper half, then you can generally go with our slim fit shirt.
Below you will find the size chart for our shirts as well as a guide to what shirt size to order based on your jacket size.
