I have to be honest, but I don't think wearing a great kilt to a formal event is proper. I have a great kilt, and the only place I wear it is to the Renn faire.

Great kilt is a historical piece of clothing. Would you wear a powdered wig and knee breeches to a wedding? A toga to Chruch? I think that the same applies to a gret kilt.

Just my opinion,

Adam
