I bought some new jeans at the weekend and have since noticed on the right leg only, on the inside of the jeans, but the outside of the leg, the seam is twisted. Like on the thigh it is stitched one way then as it reaches around the knee the seam is stitched the opposite way, causing the seam to have a twist to it. I've checked other pairs from all different stores and they all have this twist, but only on the right leg. Why is this? Poor quality jeans, or a design, to make them more comfortable? To be fair it's been on an old pair of jeans I've worn for years and I've never noticed, it's just the new pair it seems a lot more uncomfortable. Help anyone?
