Kevin 4 I’m 177cm, 78kg, and usually wear size L. I ordered XL as per the other reviews and it’s a good size. The shoulders are a little broader, but the chest is good. The sleeve length is alright, but maybe 1-2cm shorter than what I’d like. The overall length is a little long, but the ribbed bottom makes it not an issue. For only ¥3000, I think it was well worth it.
