Thank you!
I was thinking that the girl's Narnian gowns should have been nice bias-cut pre-Raphaelite dresses-- like, medievalesque, but the way the costumes would have been designed in a 1930s movie (like "The Crusades"). That way, you would have had the medieval look, with modern comfort. The dresses did look like awkwardly made RenFaire gowns, didn't they?
