Singer Ailee is hosting a special event with fans.

The video clip of Ailee's "Sweater" cover and "Sweater" music video was released on Dec. 16 through the official social networking channel ROCKET3 ENTERTAINMENT.

The video contains a total of two events. The Sweater cover can be uploaded to one of her SNS and YouTube channel after listening to the song and then follow the ROCKET3 ENTERTAINMENT account and put on the required hashtag.

Another event, “Create Your Own” Sweater, is to make a music video of your own longing and love and participate in the same way as your first event announcement.

Events run through December 31 and 'Sweater' instrumental can be downloaded from its agency ROCKET3 ENTERTAINMENT website. Detailed announcements can be viewed through the event video and ROCKET3 ENTERTAINMENT official SNS channels.

Ailee is currently engaged in a variety of activities. The concert, 'I AM: RE-BORN,' is giving fans a cozy welcome with the season's song 'Sweater.' "Sweater" is a song that expresses the most precious memories in everyone's mind through a sweater.

Ailee's nationwide tour, which also contributes to the emotions of the drama by participating in the 'Chocolate' OST, will continue in Suwon on December 24, Daegu on December 25, Seongnam on December 28, Daejeon on December 31, and Busan on January 5, 2020.
