After going through this thread I am thinking of buying a UES heavy flannel shirt (502051) from Japan. 

But I am a bit confused about their sizing. I looked at UES website and few Japanese online retailers - in most cases the measuring method is the same but reported sizes vary a lot. It seems UES size 2 or 3 would be good for me but not sure which one I should go for?

As reference, I wear size M in IH UHF, Large in Cushman sweatshirt, and orSlow size 2 overshirt.

I am hoping someone can share their (recent?) experience with UES heavy flannel shirts (14.5oz) and how should I approach their sizes. And, do they shrink after wash…
