I was even more surprised to find out that Target has wedding dresses for about $100 and they look great!

What else is out there like this for a cheap

David's Bridal. I have a few friends that have gotten dresses from David's for ridiculously cheap prices and they are absolutely gorgeous. They often have a $99 sale and you can easily get a beautiful dress for under $500. Hey, you are only gonna wear it once, right?
