Well, the colors are pink & white but I'm not sure if that's really a 'theme.' Our semi-theme is Tiffany's boxes. Every single 'box' related to the wedding will look like a Tiffany's box. Example, we're not having OOT guest bags, we're having boxes--in Tiffany's blue and wrapped in white ribbon. Same thing with favor boxes, the card box, and even the wedding cake will look like a Tiffany's box I'm going to put floral arrangements in the bathroom--pink roses--and place the vase in a Tiffany's bag.
