Hmmm, I don't have a beard, and I kind of have a look younger than I am thing going on that seems to be working ok. However, I would agree that a beard that looks good on a guy goes great with a kilt. There are though, many different kinds of beard styles, and I'm not sure they would all go well with a kilt... I might go for that "I haven't shaved in a week" kind of beard.
