So I ordered this in a medium and I am normally a large. This was a bit tight in the arms but it's wearable. A large would be too big in the body area when the medium is already pretty big in the body so the proportions of blazer are off.. What I didn't like is that the sleeves are too short. I love the blazer but I will have to roll the sleeves up to wear so it doesn't look weird. Good quality and unique print otherwise. I'm 5'6 165 pounds. Measurements are 38-32-41. Bicep is 14 inches around.
