Here’s a test for all of you:
Which pocket square goes with the tie, the one of the left, right or both?
The correct choice would be the square on the left. The blue edge is a near perfect match with one of the shades of blue in the tie. The white of the rest of the square ties well with the lightest shades of blue in the tie. The square on the left, as badass as it is, does not work. The blue in it is not in the same spectrum as that of the tie.
