Scruffy? Surely you jest! That's about as finely-groomed a short beard as I've seen. I'm serious in that. Your whole beard looks very elegant and that mustache is simply fantastic! For your event, were I you, I'd just do up the mustache as you've done here and comb the beard, perhaps with a little balm.

Needless to say, I'm glad to hear you're shooting for a bigger beard this time around.

Cheers!
Tom
