YSK: A lot of "fake" pockets are actually real pockets.

This is particularly common on suits and coats, and it is seen more frequently on finer items of clothing that have linings. It makes the garment look nice on a hanger until someone buys it and makes various aspects of transporting and stocking it less likely to mess it up. If you look/feel closely you should be able to tell, and then you can usually undo the thread - usually a very loose stitch called a basting stitch - with a seam ripper or a couple of careful snips with a scissors. Ever noticed the flap on the back of a blazer or jacket that is stiched together only at the bottom? Same deal. Open 'em up . It looks really dumb on a job interview.
