I am a petite large/xl in shirts and jackets. I ordered the Brinley in large and it fits perfect. The sleeves are just slightly long, but it’s not noticeable or bothersome. It is form fitting and flattering. The color is rich and perfect for fall. I wore it walking the dog with a tank top on a 60 degree day. There was a slight itchiness, but it wasn’t unbearable. On cold days in Iowa, I wear it under my wind and rain proof parka for wicking warmth. I look forward to wearing the Brinley many seasons to come.
