Ok, ladies I need some help. DD8 is a huge Jasmine fan, and I'm afraid our December trip will be her last for wearing princess gowns, growing up and all that

. I'm surprising them with a trip to BBB on the night we're going to
MVMCP and I want to also surprise them with beautiful dresses to wear, instead of buying them there. Not to mention, handmade would be unique and more comfy. DD6 loves Cinderella, so that's no problem. But, I can't find anything for Jasmine. Sure we have the two-piece costume, actually we have three of them I think. Like I said, she's a huge fan!
Anyone know where I can find a pattern, ebayer or someone to make one or give me ideas on how to embellish an existing something? I really want to surprise her with something special. I thought of having one made using the Cinderella pattern or even Aurora, but make it out of purples and gold.

I really would love your opinions!
