I'm getting married oct 3, 2015. Just got engaged 2 weeks ago. Mom is pressuring me to buy my dress already (it takes 6 months to order it?? EEK) However I want to lose 50 lbs (ok realisticly 30). So what to you gals recommend... buy the dress now and buy a smaller size? Wait a little bit (a month or 2)? Buy the dress at my current size and expect to take it in? How much does that usually cost?
