When I bought my dress I was about 10 lbs heavier than I am now. I intend to keep up with the weight loss and my dress won't be in for another 2 months. I have about 12 more pounds to go. I'm getting worried that if I lose too much weight I'm either A) going to be spending like $500 on alterations because they have to take so much out or

The alterations won't look right because they have to take so much material out. So just a semi-freak out that my dress will look awful on my wedding day. Any advice on this?
