I understand it is technically incorrect, and has been discussed at great length, but I prefer overlapping buttons (4 of them). Edit: The other day we had a discussion about the distance between the bottom of the sleeve and the buttons. That night, I saw David Letterman wearing a charcoal pinstripe, peak-lapel two button suit, with 2 to 2.5 inches between the buttons and the end of the sleeve. Obviously, David Letterman is not to be followed for his sartorial sense. By the way, do we know who makes his suits?
