Been trying to order a gi from Shureido USA. Their stock is very limited at the moment and they don't have the size I need. So I've been looking around other international dealers and noticed something; the sizing charts vary greatly from different sources. I'm 5'7" weighing about 138 pounds, so I need the gi to shrink down to 170cm. That means I need a size 4 (175cm) according to Shureido USA's website. However, since Shureido USA doesn't have a size 4 K-10, I looked at Shureidoweb's website (Malaysia branch). Their size 4 is at 170cm. I'm really confused. If I order a size 4 and it comes in a 170cm size, it's going to shrink a couple centimeters too small. Anyone have any experience with this?
