In case you haven’t had a chance to try this on yet: I just picked one up, and it’s still the very narrow torso that a lot of TFH shirts have. The person I talked to at SE is a similar build to myself, and recommended that I go up one more size than my usual TFH size. I went with a 44 instead of my usual 42, and I’m happy with it. It was a bit longer than I’d like, but perfect fit otherwise. I ran it through the washer and dryer today, and although I didn’t take measurements, I’m guessing it shrank about a centimeter in all directions, which helped with the length. Long story short, I feel like two sizes up from your western size is the way to go, unless you are very slim. It’s a great shirt, I’m happy to finally have one!
