Well, this is the first belther i've come across. Probably the cut though. I don't think the fabric will stretch much and normally that would mean I'd go for my usual size.
I am 177 cm, about 5,9.
Exactly 7 inches, a 1/4 of an inch more than my Thavar 8NE (31x30). Same difference at the knees.
Is your 8ne really 6.75 inch?? Mine is 19.5~ cm, that's around 7.7 inch... it's like i'm wearing bootcut
