Vintage Lined Nautica Jacket

This jacket was given to me and is pretty much still flawless despite being 20+ years old. The collar has this rigidness to it that allows it to be styled however. It says small but it fits more like a modern medium I would say. For reference, I'm 177cm, 145 lbs and it's oversized on me. Chest 21.5", Length 27.75", Shoulders 20.5", Sleeve Length 22.5", Hem 22"
