I've seen Ariel from the little mermaid in a green dress on posters and other things yet in the movie she never wears a green dress...when did she wear this dress? In part 2?? অথবা where did it come from?

I think that it was also used because that is the color of her fins when she was a mermaid.

ডিজনি gave them makeovers earlier this বছর and it caused some controversy.

This look is for the merchandise. We already talked about this and even did মতামত on which redesign was better here on fanpop. Some people hate them and some people like them. I'm one of the people who likes them, especially Ariel's. Ariel's redesign was voted the best redesign in the মতামত we did here on fanpop. Someone here did an প্রবন্ধ about the details in the redesigns.
