Despite its own collaborations, it took several years for Nora and Era Istrefi to realize a song together. Published in April of this year, "I Do not Know" seems to have paved the way for doubles performances in the same scene. Yesterday, Era and Nora performed for the first time on stage, at the Color Day Festival in Athens.

Along with names such as Eleni Foureira, Kaan, Morandi etc. Istrefi sisters sparkled the stage accompanied by two ballet dancers.

As you can see, they chose to dress just as well as otherwise.

Detail of rosy color in the shape of a "dumbbell" makes their outfits look like a matchy-matchy combination, though each one clearly preserves its identity. Nora, who has picked her short dress and shoes, accompanied by Chanel accessories, lies within her foxy lady style.

Erie, on the other hand, represents a style of Billie Eilish, with whom has been identified since its inception: athletes, skirt, lace-top crop and accessories Moschino.
