j.crew.com states that the denim is from japan. i can't agree with you, man. these look good. i've always been happy with my j.crew denim and i've just ordered a pair of the indigo raw. i will post pics and give a follow up. the 484 fit is perfect for me and the indigo raw is such a good looking color. i can't wait.
First of all, I am going to go ahead and highly recommend you don't buy the J crew selvedge. This looks like a serious money grab to me. Not anywhere on the site does it say where they are made. I have been in the denim game for a long time, and so have a lot of people on SF. And they will all tell you the same: If selvedge costs more than $200 you have the right to know where they were made.
Here is the APC PS measurements.
Even if those measurements aren't what you are looking for, you should just give us the measures for the J crew pair and we WILL find you another pair of jeans for the same price that will put those to shame.
