I love their outfits! I got Evie's from Disney Store last year while it was on sale. Evie's wings and shoes light up. Absolutely perfect at night during trick or treat. Her dress glows in the dark and I only found out when we got home from trick or treating when I turned off the light. That was a total surprise. Fi's dress was also a Disney Store brand but got it from eBay in a very good price. Her Rapunzel shoes were so pretty and fit perfectly on her little feet.
Haven't thought of what characters the girls will be next year. We thought that since Evie will be already four years old and has already a mind of her own, she gets to choose what costume she wants to wear. But the final say still depends on us. Probably, we'll just give her choices instead. That way, we are sure that she wears what's appropriate. I don't know what I want for Fi either. Another princess dress? I am still undecided. I'll see. I might be able to come up with something.
