Barbie and Ken have been a couple for some time now, so they are everyone's sweethearts in high school. They had a wonderful summer vacation together, but now it is time to get back to school. We all know how important are outfits on the first day of school, so what should Barbie wear? But the main accessory is surely her backpack, so go ahead and decorate it. Then use the perfect filters and hashtags for your school selfies. Enjoy!
