Pockets in pants or any type of clothing that are just for looks. May also be pockets that have been sewn shut. Many blazers and sport coats sold in stores have the pockets sewn shut to deter theives. Womens pants often have what looks to be pockets but are actually just stitching representing a pocket, however upon further inspection an actual pocket is not there.
