Wedding dress

I think your original dress is fine. You would only want it an inch or two longer, else it would start dragging on the floor....just wear flat shoes, it looks fine.

Agreed I found the photos of your dress and it is too short, but not horribly so. If it only looks short when you are walking I might just wear flats and try to pose in a way that your feet aren't super visible in your still photos. Otherwise Lulu's would be my recommendation for something inexpensive that can come quickly and not need alterations.
