Hi guys, today I bought a pair of G-Star Ronic, straight cut, button-fly. At home I noticed that on each leg there is one seam that includes a red thread. The red thread is not part of the fabric, it's part of the, well, seam. Other than that it looks like the seams on my other denim, which I am sure are not selvadge. So, now I'm wondering: have I unwittingly bought selvadge denim?
