I would say a black dress (Like in Nashville) or black jeans and a cute tee shirt.
Actually the one from Nasty Gal has the charm in the wrong place (it’s too high) and Rydel has had hers since before Nasty Gal had one like it in stock.
Her exact can be found here.
She wore her Exeter Cutout Boots!
Thanks for the heads up!
I hope they work out! If not I’m sure you can always exchange them!

This is the Nasty Gal shoe size conversion chart. Hope it helps!
I think you should be okay because they’re only 3.5 inches (or 8.89 centimeters), so they’re not too terribly high. So unless your school has a rule against them you should be okay.
It’s perfectly alright sweetie! <3 They fit true to size and they’re really comfortable. I can walk in mine for 8 hours before my feet even start to bug me in the least. 
It’s alright! It’s right here! And thank you so much!
Working on it!
Working on it now!
I have several in the inspired tag but I’ll make you one just for you! And thank you!
