Super Rare Muuba European Style Moto Jacket

I hate to part with this jacket, and I’ve looked high and low for one size up, it cannot be found. I love it, but it’s just a touch too tight for me in the shoulders. I am a medium so don’t let the size deter, I have a 34D bust size, and a 27 in jeans. measurements shown. Heartbreaking, needs home where it will get worn. Bought brand new, only wore it a couple times, literally brand new :( Sleeves are gusseted, armpit to wrist, arm tightness will never be an issue. Says US0, but more like a 2/4.
