Next up we have this feisty red two piece worn by Ariana Grande at KIIS FM’s Jingle Bell Ball. Grande also wore her signature half up-half down ponytail, white feather cuffs and white patent heels. Not only did this outfit have my 12-year-old self in awe, but this moment itself is one for the books. As a reminder to anyone that had been living under a rock in 2014, this outfit was worn as Ariana performed, with then-boyfriend Big Sean, their song ‘Best Mistake’, confirming their relationship in the most heart-warming way ever. There truly isn’t a better iconic Christmas moment than a dramatic display of love!
