When I think of disco, the words "elegant" and "fancy" don't really come to mind. I had to make it work for a recent cake though. The co-worker who ordered it sent me the invites to her 50th birthday party which were black with white filigree. She wanted it to match the invites and incorporate a disco theme, plus a high heel and dancing steps. Lots to put on a cake, but I think I pulled it off.
