Sizing Advice on J.C.F. Unconstructed Linen-cotton Blazer

[MaitreTea]

Thinking of pulling the trigger on this unconstructed linen-cotton blazer from J. Crew Factory, which I think was featured on Joe's "Best Looking Affordable Blazers of Spring 2015."

Can anybody who has one of these speak about sizing?

I'm 6'1" and I wear a 42R with the other J.Crew Thompson suiting. Should I go for the medium or large?

If you wear a 42R Thompson, you should go with Large.

What about a 46R in slim/tailored fit on other brands? Would XL be too small?
