Yeah, I haven't had any success finding those exact pair. It may very well be that they are vintage because that wash isn't as trendy these days.
However, in my search I did find these wide leg Seven jeans that come with a design near the front pockets and have a seam running down the entire length of the leg that look similar to those ones, only in a darker wash. No idea if you'll like them or not, but I thought I would share!
