IU was recently chosen to be the model for clothing brand, "Lecoq Sportif", and a few photos from the filming set were revealed today. She's put aside the more mature look she's been wearing for her "Good Day" promotions lately, in exchange for a fresh and sporty style that makes her look her age. Like any other teenage student, the images show the singer dozing off in class and scribbling on chalkboards. A representative of "Lecoq Sportif" commented, "We focused on expressing IU's cute image to fit the concept of our brand.� IU returned to her student status for the shoot, giving us a lot of lovely shots."
