I am looking to purchase 2 princess outfits (sleeping beauty & cindy) for my 9 yr DD. She is thin but tall so would probably need approx. size 8-10. I don't mind paying the money, but I want quality. Any suggestions? Advice on dresses at the park? Can anyone compare park dresses to the dresses from the website www.mydressuptrunk.com that was posted on this site? The dresses at my walmart do not come in the larger sizes.
