if you want a more snug look size down i mean really. medium was perfect im 194 pounds 6”0” i hope this helps

This is such a cute windbreaker.! I love it! If it had different colors I would purchase more. It’s a very light jacket and the block color of blue really shows its character! I wear a size XL my breast our big and it fits perfectly and I can zip it up without it being tight it’s definitely loose which is good.
