For once I want all girl characters in flats. Ballet flats are the easiest. Payless Shoes has some that are perfect. http://www.payless.com/store/product/detail.jsp?catId=&subCatId=&skuId=065551105&productId=64036&lotId=065551&category=&catdisplayName=Girls
If you do a google search and come across the website Tudor Shoppe they also have great shoes for sale. There are also costumes on the site but they tend to be anything from expensive to REALLY EXPENSIVE!!!
If you do decide to order a costume from Tudor Shoppe please do not order the Fleur de Lys Dress. I have ordered it for the Stepsisters, and I certainly did not pay that price! I managed to bid on two from ebay!!!!!
