The more features one finds in the jeans could give clues to their authenticity. YKK or self branded zippers would appear genuine. If there are multiple tags then this is a good sign. Miss Me jeans in particular have a belt loop at the back which should be positioned directly above the rear gusset seam. There should be a stitched stylized M logo on the coin pocket and all riveting on the jeans should show a logo or pattern on the rivet. The rivets should not be plain.
