Where can I find, either in store or online, a Little Mermaid costume?

Preferrably I want a non-traditional mermaid costume. I want one from the movie, like the blue dress at the end of the movie that she comes out of the water with. Or the dress that she has on when she is touring the kingdom with Eric. Or the pink dress that she puts on after she's rescued off the beach by Eric and takes a bath. If someone could help me with that, I would really really grateful.

If you've seen Napolean Dynamite, then if you remember the dance scene when Napolean's dancing with Deb. Try getting a dress that kinda looks like that. There's a chance you might have to make the dress yourself. I wanted to be Ariel last year, but all of the costumes were too small. Apparently I've outgrown the 5-year-old size (I wonder why....). You might have to pass up on the idea too. Last year I ended up being Wednesday Addams, later a Fortune Teller. I had Tarot cards and everything. Try doing something that you can't buy, that you use things from around the house. It'll end up a lot better than you think.
