Hello and a warm Celtic from Boston, Massachusetts.
Listen to She Who Must Be Obeyed. You will be fine in the kilt. After you wrap that garment around you, you may not want to take it off. As you may notice, many of us on this forum proudly display ourselves kilted on our avatars. My fat old body is as "pasty" as they get, and I still get the lassies complimenting the kilt as am about town. It is great way to be.
