I have this dress I wanted to wear tons wedding sat but I tried it on and I thought it looked ok bc I am pregnant but the hubby had a funny look so what are you thoughts... Wear a dress that is not so form fitted or do you think it looks ok? My sister said get bigger underwear : ) and don't mind the messy room!!
