The only pinning and attaching that bothers me is not with packaged shirts, but more casual shirts on hangers that I might want to try on in the store. They have some of them tagged/pinned in such a way that you have to remove the tags because they go through the button hole, around the button and back out in such a way that you can't unbutton the shirt to try it on. You also have to take out a dozen pins and tabs holding the collar closed, etc. Then you have to leave all this in a pile in the dressing room and return the shirt to the rack all undone.
Art has a double face, of expression and illusion.
