Less is More
There will be plenty of time later in life to pack on the eyeliner and rock a smoky eye day and night. When girls are younger, less is definitely more. For school encourage a minimalist look, aka mascara, sheer gloss, and a bit of blush. For special occasions you can up the ante a little bit with a little sparkle on the eyelids or a neutral shadow. Just stay away from bright colors or statement styles like strong red lips or smoky eyes. Save those for your adult years.
