Well, i assume you will dancing up a storm.
That dress is so striking that everything else can be pulled back and a little understated, to simply showcase your lovely figure and face.
Ahem...double sided tape for the cleavage :-).
And to make that wonderful long line even longer, perhaps a high top knot hairdo? A good hairdresser can make one that will last, and maybe a soft black feather or a chain in it.
If you decorate the hair, no need for earrings or necklace, just a bold bracelet.
Waterproof makeup where possible, so that for me usually works out to no clumping waterproof mascara, a gel blush, lip gloss over a matte dark lip stain, and very little to no foundation, depending on how you feel about your skin.
That should do it for all the photos, but not run and look bad if you rock out. Have a wondeful time!
