Runs small. Initially ordered 44r - all my suit coats are 44r, and all still fit well, which suggests that the coat is sized small and that I have not "grown". Reordered 46r and this one fits well. In short, order one size up. Looks great with dress pants and jeans alike, giving you options for multiple occasions. Subtle western styling sets this coat apart from the rest of your sport coat repertoire, but not enough to make folks assume you're a professional bronco buster.
