I wouldnt want to be too matchy-matchy with all the black so the silver shoes would be better than black.
also for jewelry i would do some little things with really bright colors to add that to your outfit because if you dont have some color in there people are going to think your emo. i really like purple (myfavorite color) but any color goes good with black and white so whatever color is your favoorite, aseccorize with it. But dont go all crazy with like ten different colored pieces of jewelry. Sstick within the same family like purples blues or reds yellows oranges. Nothimg like green earings purple bangle red necklace magenta headband ect.
