#6 Ariel and Prince Eric from The Little Mermaid
Though not carbon copies, these two sets of attires have undeniable similarities with the original outfits worn by human Ariel and Prince Eric from the movie The Little Mermaid. Like human Ariel’s set of clothes from the film, the twins’ version includes a long-sleeved blouse and a dark-colored bodice. But instead of adding a foot-length skirt to the mix, the siblings opt for a knee-length denim skirt that gives the getup a touch of rustic charm. The sisters’ version of Eric’s outfit, meanwhile, replaces the original’s red sash with a leather belt, which helps establish the attire’s vintage theme.
