I agree with Debbie and Janet. Bridesmaid's dresses are temporary. Being healthy and feeling good about yourself are forever. So...stick with us, and you'll be on the right path.

And by the way, based on weddings I've attended, nobody will be paying much attention to the bridesmaids. It's somebody else's day! So don't worry about it, surround your friend the bride (and/or groom) with happy thoughts, and have a great time!
