Recommend one size up for loose fit and your size for tight fit. Have ordered two for me and one more for my friend.

I wear M size shirts so I went for 38 size jacket. First it was bit too large, but after washing it on 90°C it shrinked and now fit is perfect. I love the fit of this jacket.
I am really satisfiend
