You have your dress and now it's time to get all the details just right. A good resource for vintage dressing from head to toe (and a little extra fashion info) is at Fashion Era. Speaking of toes, a great way to cover them is with shoes from Remix Vintage.
But before you go down to your toes, you should think about what will go underneath your fancy dress so it falls right on you. If you have a vintage dress, it is important that you have foundation garments as ladies of the past always wore foundation garments and hosiery. A great place to get both is at What Katie Did (I don't think I need to tell you that that this link is not work safe).
If you want to go the full 10 yards, you can also top your style off with a wonderful hat. I tend to get my hats off Ebay or make them myself. But if you want to buy new hats, here are some links:
