Found several options and bought all of them (they all have other re-wear value) but I think the best one is a black-and-white print (the internet tells me that those two wrongs make a right); the internet also says pairing it with black shoes and a black cardigan is ideal, which is good because that is all of the shoes and all of the cardigan* I currently own.
I actually managed to get a female friend to come shopping with me and she said it doesn't look remotely bridal or upstage-y (none of them do, though another of the options would have to be altered a bit because it does a bit too fabulous a job of showcasing my cleavage as it currently is).
