Obvious answer is for everything to go smoothly; for the people we care about the most to make it to the wedding. But in terms of planning, a great and affordable venue and photography. Though the wedding is one day, having good pictures to remind you will last forever (hopefully).
I think everything in my wedding plans is very very important.We should pay attentions to the details of a lot of thing,such as wedding dress,wedding gifts,wedding cakes etc.
The most important in them should be the wedding dress,it will make you be the star of the wedding,especially the white wedding dress it will make you like an angle in the world.How about this one: http://www.asapbay.com/strapless-ivory-brush-train-princess-wedding-dress-b12039.html
