I oringially did not want a strapless dress and planned on a two-piece, but I ended up getting the one in the picture below, but more of an A-line style than a ballgown. I've included some hairstyles and a picture of me (the top left b&w one) if that would help.

I am not a fashion expert by any means, but may I suggest wearing some of your hair down in front, like ringlets, but not enough to detract from the beauty of the lowcut dress. the rest of your hair down your back. You have lovely hair and showing it off works well with a low cut dress.1
