You already have 31 and its loose? loose on the waist or loose on the legs? What size are you on ther vikers?
I have 887k in thanaz, the probelm with the jeans is the legs, ecpecially the knee and calves area, which runs really thigh. Its stacking behind the knee, and the calves really thigh, it almost looks like legging. Evrey time I stand up I have to pull down the jeans. Did I menstion its size 33, while other skinny cuts I have are size 32 and much more looser on that area.(I train and runs alot, I have big calves, but I never faced this kind of problem on other washes, even on thanaz) The waist is kinda loose, buts thats not really a problem(for other people al least :/)
