A teen girl room should have several areas organized a lot of functionality: a sleeping zone, a studying zone, a vanity and a closet if necessary, and maybe an area for guests. Separate the areas to give your girl more comfort and organize them to make them more practical. Add storage cabinets on the sides of the bed or go for curtains to separate this part of the room. Another cool idea is placing the bed by the window creating a wonderful sleeping nook, so your girl can see stars. Your girl will add LEDs, photos, pictures and other stuff she wants in her sleeping nook to make it cozier. Make it girlish: go for a cute desk, bold pictures or photos, make a gallery wall, add a fur cover to the chair and some little glam accessories that she will like.
