How can you be satisfied with a handkerchief that you can't blow your nose in? In preparation for the formal dinner, I looked at recent photos of the tuxedos. It looks like 2019 is only trending for a white pocket square with square pleats, so this is a good choice to look simple without the pleats and irons. The size is exactly as stated. Measure your pocket. The first one I bought was a bit big so I bought a smaller one.
