I want a great versatile black maxi dress for pregnancy at a decent price. I almost bought this one, but didn't feel great about the reviews complaining about weird ruching on the back: http://m.oldnavy.gap.com/product.html?dn=op1236150120002&cid=81835&pid=1236150120002

Any suggestions? A dress you love? Maybe I should just shop in regular clothes and buy a larger size maxi?
