The holiday season is officially here, people! Tonight, the 16th Annual Christmas in Rockefeller Center event airs in New York kicks of—and marks what seems like the millionth time Mariah Carey has performed in front of the famous tree. Ever since her version of All I Want For Christmas Is You dropped in 1994, MC has been the queen of rocking a holiday ensemble. So, it's time to look back at the Mariahs of Christmas past—from her Santa crop top to this year's Cruella de Vil-esque gown. Ladies and gentlemen, the princess is here.
