I live abroad and went home for my best friend's wedding last September (2010). They had to order my bridesmaid dress based on my measurements and I didn't have a chance to try it on. When I got home, I tried the dress on - five days before the wedding - and it wouldn't even zip. I thought I was going to have to wear a sweater over it. Luckily a good friend and very talented seamstress took it out all the way and I wore it, but it looked awful. To boot, I was convinced that the size of the dress was too big and it would need to be taken in!
Her entire wedding day I knew I looked awful, and I look awful in the photos. That was it for me! Came back and hit it hard and have lost 40 pounds and still going.
