If the gorge of your waistcoat is reasonably high, a jabot can look just fine with an argyle (IMHO) and will lend that certain air of je ne sais, what do you call it to your rig. They are really quite easy to make- any bit of lace will do. Someday soon I am going to prepare a tutorial showing how an ordinary piece of lingerie can be converted into a jabot in mere minutes. It can be a true lifesaver.
