We design our shirts (and jackets) based on the principle that when a shirt fits the chest well, this lays the foundation for a better-fitting shirt overall.
Tailoring to chest circumference provides a trimmer fit to the body. A higher arm hole allows for the sleeve to be tailored in appearance, rather than baggy. We think we nailed down a tail length that looks smart both tucked and untucked.
Though we try to keep sizing standardized across every shirt we release, there are some exceptions. We suggest referencing the Size Guide and Specs for a particular item before ordering.
