I am due 4 weeks before my wedding. I have thought a lot about what dress to get with bf etc but need to order it 6 months ahead. My question is what size? I read somewhere to get measured at 4 months for your postpartum size. Is this in anyway accurate? Im goig for a lace up dress which I am having zips put in for easy access so I will have a bit of room to play with.... help!
