Not girly, need advice on prom-related biz...

So my senior prom is in exactly one week! And when I say exactly, I mean down to the minute (7:00 p.m.). I have bought my ticket, taken care of getting a ride (though the date part fell through) and all that jazz. My biggest concern is how I'm dressing. I have bought my dress, as you can see down there v v v, but I don't exactly know how to accessorize. I don't want to go in just plain black (which is the color of my dress.)

I have asked my friends, and my mom, and even my brothers, but now I am asking Mibba to help , because, well, I can. I'm just asking everybody., really So, please, do give a tomboy some pointers on how to make this dress work for Prom, and how to look totally kick ass XD

My dress:


I was thinking along the lines of adding some red, I don't know.
I'm totally hopeless, sorry...
