I found the dress of my dreams a few weeks ago and decided then that I would come back and buy it two weeks from then (which is about now). Since then I have lost about ten pounds accidentally (I stress-lose) and it doesn't seem to be stopping. Should I buy in my current size, expect to gain it back, or wait for my weight to stabilize before investing in a dress? I had planned on losing 10 lbs for the wedding, but I was hoping to do that over the course of 10 months or so, not all at once, so now I'm not sure where to expect my weight to be in October. The time span matters because my body always looks different if I lose weight slowly vs quickly. Is altering expensive?
