Oh yeah baby, feels good to let it all hang out. Starting to get a serious belly on me (I am seven month pregnant after all). So we adapt to the expanding waist line situation and we go with whatever works, whatever feels good. A skirt worn as a dress is always a good idea when needing to hide something, not to mention the comfort factor.
I mostly opt for skirts or dresses when reaching the third trimester. Otherwise your favourite jeans can be worn with a belly belt and a long top. I have a couple of pairs of jeans in two sizes up for this stage, comfort is imperative.
