Hi Melissa -
I found a great dress at Macy's Bridal Salon in the Smithhaven Mall. Its got silver in it (I know you said you were looking for one with silver/platnum). Its made by Maggie Sotero. You can check it out at http://www.maggiesotterobridal.com/images/MT92594.jpg . Its around $690 at Macy's. Hope this helps :)
