Would this be a cute outfit?(for a 12yo girl)?

Yeah! Deffinetly!! I love to wear really cute outfits for school and it takes me like 30 min to get dressed (lol) but I think your outfit would look awesome, just the shoes is what I think might ruin the look. Your look is stylish and cly but the prints are a little more "out there" Maybe a pair of black flats or some boots (like UGGS) would look great!!! Hope I helped!
