Nicely made shirt. I usually wear a medium, but sometimes I have to go up a size in western shirts because I don't want it to constrict movement through my shoulders when Im riding. I ordered a medium and a large through Prime Wardrobe so I could try both. Both would have worked but the medium really fit perfectly and was loose enough across the upper back, while still being tapered to fit nicely at the waist. Im keeping thevmedium and returning the large. This is ithe first time Ive used Prime Wardrobe and it worked really well!
