This New Year's Eve, Taylor Swift threw one of her epic parties and asked her guests to arrive in a costume representing their childhood hero. Lucky for us, a mini Swift enjoyed watching Disney's The Little Mermaid and dressed as Princess Ariel. While it's rare for the singer to not pull off a look, we were especially impressed by how well she pulled off the long red wig she paired with her signature red lip. Considering that Swift also wore a red wig in her "Babe" music video, we're hoping this means the star is considering this hair-color change in real life.
