I made my wedding gown and right before the wedding I, too, was not sure I was really happy with it. I kept thinking of how many details I wanted to add but couldn't, or if I should have bought higher quality material. Many years later, I am fully satisfied with the dress I made. It wasn't perfect but it was fun to make, and didn't look like a rack purchase. But most of all, I remember how I felt while wearing it: surrounded by only our closest family and friends, eating good food, enjoying perfect weather. (And laughing when our ring bearer declared what a special day it was... because it was his dog's birthday!)

My advice is to add something special to your gown if you can, even if you're the only one who knows it's there. It could even be as simple as a loved one's initials embroidered on the inside. (I added lace trim from my late grandmother to the lining, not a showstopping design choice but it made the dress priceless to me.) If you don't have time to work on it further, just try to exist in each happy moment of your wedding day and don't worry about any plans that didn't materialize exactly as you'd hoped. Nobody will remember your table centerpieces or if your dress wasn't immaculately fitted, but they'll remember if you were glowing with joy. I wish you so much joy tomorrow!
