She may have the same practical objection my wife did at first, cost. She objected strongly to the idea of spending hundreds of dollars on one garment when I can get jeans for $20. I convinced her that buying one casual kilt would give me a chance to study it and then I could make my own. She really hasn't had any problem with it since and rather likes the look. In fact, her only concern now is how it'll work out during the cold weather. She's never been concerned about what friends and family think of it and there's been no problem in that regard at all. Do have a heart to heart with your lady and find out what her real objection is. It might be entirely different than you think.
