they ARE cute. and definitely wearable for school!
It's not like they're red stilettos that you're rocking "out of the blue"
just make sure to wear a normal outfit so that the boots won't be all crazy! like, jeans and a casual black tee... that way the rest of you is comfortable... and most people won't think anything of it
honestly... i remember a day i wore a leopard jumpsuit to school. i was shameless about it, and a few people were shocked i wore it (looking back, i would have been too!) but people don't remember what anyone wore... by next week, it wont even be a thought in their mind! GET IT GIRL!
