Maternity/ nursing dress help

Hi I'm due in July & have my brothers wedding & a christening that month too. Has any1seen any nice flattering dresses which could b maternity or suitable for after having a baby? I've got a big bump & I know I'll have a lot of wobbly bits to hide after the baby is born so need a dress to cover quite a few bits! As i dont know if ill b pregnant or if il have had it by then! Any ideas? Thanks
