Not sure what you mean by modern, but avoid the BD and get a formal shirt. I like LK's approach to using a color other than white for the shirt. I think light blue, light pink or off-white textured shirts can be good, tasteful alternatives. I also think turn-downs look more modern than wing collars. You may want to look at getting slippers, perhaps in velvet, especially if you decide to play it straight with the rest of the outfit. A pair in maroon or green could work.
You don't really have much time to play around with the outfit, so the advice to keep it simple is a good one, especially if you are with a date. We forget that it's her and her outfit that's supposed to draw attention. You're there as a companion and an inoffensive accessory.
