Outfits for school??? what do wear with these pants?

I would wear a tight, white colored shirt (tank, cami or short-sleeved v- neck). Something plain and tight-fitted would look the best to achieve the sporty/causal look. As for your hair, I would either wear it straight and down or back in a highish ponytail (and maybe wear a cute, fabric headband). I would wear minimal jewelry, maybe a simple stud earring (if you have your ears pierced) and possibly a simple chain necklace with a subtle, small pendant too. Hope this helps! :-)
