All of our mens shirts follow standard sizing measurements. With width being across the chest, armpit to armpit, and the length being from the back collar to the hem. For full chest size, simply double the width for an approximate value. The majority of our shirts will have a Euro-style fit to them, this equates to them being slightly less billowing than a US-style shirt. While the majority will not notice a difference, people on the border between two sizes may feel more comfortable in the larger version. If you are unsure of which size you might be, or can’t decide between two sizes, we suggest taking the measurements shown on the image below on a t-shirt that fits you well.
