Don’t want your child to bare too much skin by going as Ariel from The Little Mermaid? She doesn’t have to with Ariel’s blue dress Disney costume! If you can remember, Ariel wears a blue dress when she transformed into a human with humanly legs. Her dress just needs to be sea blue that goes all the way down to her ankles, and don’t forget a blue headband, or starfish, if you want Ariel to be more recognizable. And don’t forget, what makes Ariel stands out is her red wavy locks, which would complete the Disney costume!
