I am 5 feet 9 inches tall and weigh 115 pounds. I am looking for a long form fitting wedding dress. I want something that has a low back and also is bery flattering in the bust area. I have looked online through various websites and did not find anything at all that caught my eye. I really do not want to spend to much money. I want to keep it sexy yet elegant. Where can I look to find what I need?
