I love anything Disney! So I had gone through most of the princesses while in college, and as a mom, I thought it would be fun to let my little ones be the princesses and I could be the evil villain. I had enough materials left over from other projects that I was able to make up the costume completely. I made the tentacles out of black felt that I had purchased for a poodle skirt and then I lined them with lavender satin so that it looked more slick.
Then to make it more the correct texture of her tentacle undersides, I sewed a seam every few inches, leaving the underside with ribs. I also painted on sparkly purple suckers. When I created the tentacles I sewed in a narrow channel to put wire in, so that the tentacles would sway as I walked. I then lined the costume with an old skirt that I wasn’t using. I added a button to the back of the costume so it was basically a strapless dress. To accessorize I found a large sea shell which I drilled a hole in and strung on a black thread. And I found cool sea shells which looked like chandelier earrings. I painted these with purple nail polish and then bent a straight pin for a hook and put them on a pair of earrings.
I spent more on makeup than materials for the costume! People still talk about it!
