What do you wear to a sweet sixteen?

Well, it depends if it's formal or semi-formal. You can never go wrong with a little black dress, though! Dress it up with a statement piece of jewelry and cute heels. If you want more ideas, I would definitely suggest checking out renttherunway.com. You can rent super cute dresses for all kinds of occasions and only pay around 10% of the price. You get to rent the dress for 4 days and they even send you two sizes just in case.

(BTW, I'm not working for/getting paid by Rent the Runway in any way)
