You can do an empire waistline dress that is baggie in the belly, you can do a baggie shirt and a cute mini skirt with boots, you can do a long baggie dress and wear leggies underneath and flats or boots. A wrap dress would be pretty too and would hide most belly bulge especially if it is black. You can wear a spanx too if you think it is just a bit and can be sucked in. You can buy spanx at Dillards, Stein Mart, etc Wear a nice, tight, cami underneath to help suck in your belly and leave no creases or lines. I think shirts and skirts are best b/c you can't see where your belly actually is bulging. You can also wear a sleevless dress and wear a cute jacket over it. You can get cute jackets at Ann Taylor Loft, Old Navy, New York and Co, etc Wear a waistlength cute jacket that just hits the top of your pants or right below for that little side/profile coverage.
then, don't worry about it, I am sure your husband will think you look great anyway! have fun!
