It’s no secret Disney’s Frozen has become a phenomenon, but new statistics are proving just how lucrative it’s been for the company.

Disney Consumer Products has revealed that more than 3 million costumes of the film’s main characters, Elsa and Anna, have been sold in the past year.

According to Street Insider, these costumes lead in all Disney Store locations in North America by the double digits.

The Elsa and Anna costume trend was a big one this year on Halloween, as the National Retail Federation’s 2014 Halloween Consumer Top Costumes Survey reported 2.6 million youngsters planned on dressing as the ice princesses.

Outside of North America, the “Let It Go” has been downloaded on the Disney Karaoke: Frozen app more than 3.2 million times in more than 100 countries.
