I don't know much either. I chose to buy Bluchers, which are often mislabeled Oxfords, for an all perpose, black dress up shoe. Here's the thread from way back.

Not wing tips, but hope that helps a little. They seem to be fairly good shoes.

For actual formal attire, tuxedo, you might go with real Oxfords that are very shiney.
