accessories help :D

a while back i posted that mum isn’t getting me a prom/formal dress this year, and that if i cant find/think of anything to wear i would borrow a friend’s long black dress. but.. i THINK i have what i want to wear sorted out.

[Click here for photos!]

this is just a normal flowy black dress, with the bust bit pulled down since its elastic.the white bit is just a plain white lace singlet. which Im gonna wear a plain strapless bra under it. most likely a black one.
and the belt is just there to kind of hide the elastic

so what do you girls think?
if this is my final outfit for my formal. what shoes and accessories should i wear?
