I'm planning a fairly low budget wedding and I don't want to spend more than 800 dollars or so on my dress, and that is after the cost of my alterations. Therefore, I am trying to wait to buy a dress until after I lose about 15 lbs. I've already lost 25 lbs since getting engaged, but it took me 6 months. My wedding is in a little less than 8 months (September 10th). How long can I wait before buying a dress without pushing it?
