I was unfortunately delayed, but I think I've compiled some beautiful choices for you. Perhaps one of the dresses will work for the wedding, provided the colors aren't off. I did include some choices in a soft pink, which might be vintage enough to suit you and be wedding worthy.
Some of those choices are definitely not cheap. If there's one area people shouldn't pinch pennies with, it's looking their best. And a few expensive pieces can go a long way, when mixing and matching them in a wardrobe.
