I know a Mormon who wears a kilt. He's a friend of mine who owns the Denny's in the town I grew up in (Durango, CO). The first time he saw me in my great kilt he went on for about an hour about the first time he wore a kilt (in his hometown of St. George, Utah) and how cool kilts are. We'd have to ask our Utah members, but I don't think you'd have a lick of trouble.
