I wanted a nice show shirt for days when jackets are excused. This shirt is perfect. It's beautiful without being too over the top. I think it may run a bit on the smaller size scale much like most riding shirts. I wear a medium in street clothes but ordered a large in this and it is snug. Hope this helps.
Rated -1 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is True to Size and 2 is Runs Large
