So I originally ordered a size medium based on reviews and sizing chart, but in my experience the size chart was not accurate. I’m 5’7, 165lbs and chest size 38-40. Being that this style is not a slim fit, the size medium was way too baggy and the sleeves were excessively long. I exchanged for a size small and it fit like a glove and I can still comfortably layer sweaters and hoodies underneath. The sleeves are a bit too long for my preference, so I’ll be taking it in to get tailored. Overall, it is a beautiful jacket and one that stands out in my closet amongst my other leather jacket brands. I’ll definitely be purchasing another Schott jacket in the future.
