My best friend's wedding is coming up in September, at which point I will be about 7 months pregnant. When we ordered dresses, I was still newly pregnant and not showing at all and considering this is my first baby and I had absolutely no idea how I would grow, I went with the salon's advice on sizing. At the time I was measuring an 8, she ordered me an 18 with extra length (I'm tall so I was okay with it). However, now we are about a month out from the wedding and the dress is still way too big and will need some major alterations, but I still don't know how much I will grow in the next month. If you've been a pregnant bridesmaid (or just pregnant in general I guess), when would you suggest I pull the plug and get the alterations done? The salon where we bought them only does bridal alterations so I need to find a different place, but I'm not worried about that.
