I wear a kilt to church pretty regularly and in all the times I"ve done it, I've received only one negative comment. That was from a 7-year old girl who was cranky 'cause her mother had just given her what-for for doing something...I don't even know what. I do get the impression that my Scottish friends David and Doreen think it's all a bit of a poser-act, but they've never actually said anything. I note that David never, ever wears a kilt, though David Jr. owns one.
