IU has long held the title of "Nation's Little Sister." She's the complete embodiment of the young, innocent, fresh-faced, and flawless beauty look that dominates the K-Pop industry. True to keeping with her nickname, IU's look is striking and beautiful, but always stops short of being too glam or overtly sexy.
She accentuates her big doe eyes with just a dash of liner on the top lid and keeps her brows straight and well-defined. Her hair is never fussy, and she prefers to keep it long and tousled, adding to her simple look. While it;s likely that one day Nation's Little Sister might evolve her style to something a little more mature, for now, IU's approachable, everyday look is what everyone wants to emulate.
