Can you spot the theme here? Tough as they are to tie or to keep on straight, bow ties look dapper on some people. Not sure if it's my best option. I would think that the advantage of their size and shape has to be that they are much more difficult to splash soup onto. I find that clerical collars are handy at potlucks for a similar reason--green jello or a perogie tries to leap off the plate and the collar isn't likely to take the hit. Perhaps this could be my contribution to your apropos of nothing file. cheers.
