It's just always a small risk, to buy clothes in the network, even if you can convert it, not replace the fitting on site. Mostly I decide after reading other reviews and usually "works" it then also. This time it did not quite work: the length does not match the length that I am used at 32, it has fallen a few centimeters too short. 33 for the waist is fine, only the upper part is also advised shorter than usual (about 34 in).
