I got this in a size L and I’m about 175cm tall, 50kg. In western sizing I’d usually wear a medium for the same fit. I love the cut of this shirt buuuuut you kind of get what you pay for quality wise. It is even thinner and flimsier than it seems in the picture and mine arrived with a lot of loose threads. I also had to try to stitch the collar down myself cause it was quite warped. It’s also extremely see through. I don’t think I’d buy this shirt again, but now that I have it I’ll find some use for it, even if it’ll only be as a pattern to sew my own version of it in a better fabric.
The quality is excellent, will be ordering more.
