Teens i need advice.... going to a formal dinner party?

i like the first one. it is much clier. Dillard's always has a nice selection of dresses as does Macy's. with the first one i would choose some y all-black pumps, with some black drop earrings and maybe a small necklace, a small silver chain with maybe a little black pendant. nothing big. no bracelet. hope everything goes well:)
