In his case, OUT, but I'd fix the look of the sporran pocket in front. Otherwise, your hubby is such a fashion victim, I'm suprised the Tartan Police haven't drawn a chalk outline around him yet. He looks a bit rumpled but I suspect he's more into comfort. With a Utilikilt-type kilt pretty much anything goes. If you ever get him to wear a traditional kilt post a pick just for comparison sake. I imagine a more RenFest style would look better on him (tartan kilt, waiscoat, poplin shirt with collar).
