When a linen handkerchief is worn in an outside breast pocket, it is a "pocket square." When the same item is worn in an inside breast pocket, it is a "handkerchief."
We are never to confuse the two. The inside article may be used for hygienic purposes, the outside may not. Of course, should you have a tearful female witness on cross, you probably should pull out the outside version to gallantly offer her, rather than the one inside, or risk the tearful lady thinking you might have used it already yourself.
Ah, then the pocket square returns to its origins, provided it is cotton or linen, since it is doubtful that even a chivalrous member of the bar would sacrifice that silk Hermes number thus. In that case, grab the tissue box off the clerk's desk:icon_smile_big:
