Many times the vent (flap opening) at the center back hem of your coat, is sold 'tacked' closed. It is sewn with a loose stitch to keep it from coming apart during shipping and getting creased. (Manufacturers stitch the pockets closed as well.) This stitch is NOT a decoration! You need to cut it and take it off your coat! Now. Please.
