Singer IU is giving a sneak peek at her 2015 calendar via her official fan cafe, 'Uaena', with two photos from the actual calendar, garnering much attention from her devoted fans. 

In one photo, IU is wearing a laced crop-top, yellow skirt, mickey mouse ears, and a burgundy turtleneck, while she went the lovely route in the other with a pink flower in her mouth. In both photos released, the idol confirms her showstopper image.

Loen Tree revealed that IU will be displaying a more mature charm as she sheds her innocent, "nation's little sister" image through the calendar.

Meanwhile, IU calendars are available for reservation and will be available on and offline on December 17.
