I am 178cm height, 73kg, with a 188cm wingspan. I was having a hard time finding a gi that wouldn't eventually shrink past my wrist without being too big everywhere else. In fact, Kusakura who prides themselves on providing over 100 sizes for 99% of fits did not fit me according to their standards custom measurement. I would have had to custom fit order a gi marked up 50% for them to give two full sizes to my arm length (which is hard to believe so I was nervous dropping that kind of money with no returns). Fuji arms were just way too short to fit my body and returned that. However, I tried the IJF Champion Gold because their staff said this would fit, and it does! I measured 172.3cm wingspan out of box and after 4 cold washes it has stabilized at 167 and is right at the wrist. What a relief! I have also got many compliments at the dojo on the gi which is a nice bonus.
