The pocket square dilemma. To use or not to use.

You do not use it actually. A pocket square is usually a fancy name for a silk, linen or cotton handkerchief that basically sits in the left breast pocket of your blazer, sports jacket or suit. I suppose that handkerchief's main purpose is to accessorize a blazer, jacket or suit jacket. Somewhat like a lapel pin or a  boutonniere which accessorizes  the lapel, this does it for the breast pocket. But this is actually more important than one that sits on the lapel. I'll get to explaining that later.

Anyway, the pocket square is a handkerchief that sits in that top pocket. Do you actually take it out and use it? You could. But then if you've folded it nicely and you like the way it sits it would be wise if you actually carried another hanky that you could use. Like I do.
