I also want to know where she got her dress. That is a very very lovely design. Looks like a pattern I have been wanting to use.
So random, but I think Renaissance Fairs have become the place for "dress up time". You now see Star Wars people, random fantasy characters, anime cos-players, punk-Goths who are not punk-goth in real life but just dress that way for the Fair, and even other eras along with your normal Renaissance/medieval period fair goers. It is such an odd assortment.
I am not surprised pony cos players are showing up at the Fairs.
