I still haven't bought maternity clothes. I just went to my usual dress haunts and got a medium (I'm usually a small) or a size 6 (I'm usually a 4). From the front, I don't even look pregnant. From the side, well, there you go—the big baby belly bump!
The secret to looking slim while pregnant is black, black, black! Y'all know that black can make you look like a model for weight loss pills, and pregnant Hollywood stars often turn to black to avoid looking too big.
If you don't like black, stick to one color since it fools the eye into thinking there's one long length of you. I like dark green, navy blue, gray and white! I am especially fond of this Karimadon with a big red bow on the chest--makes my new chest look even bigger, but in a sweet way!

Busy patterns, which pregnant women seem to be fond of, just widen you. So avoid them. If you do like patterns (like me!), get the small kind—you know, tiny flowers, little paisley swirls. Do not get clothes with huge circles, big teddy bears, big flowers. Also, remember that you're carrying a baby; you're not the baby. So choose sophisticated touches, not prints that toddlers will wear.
Choose clothes that are tailored—yes, it's possible to wear tailored clothes even while pregnant. Just look at this black dress again.
You don't really need a lot of maternity wear anyway. I think I rotate about 10 dresses. Silk jersey dresses, soft knitwear, comfy cotton—clothes that flow over the body or those that show off just the boobs or the tummy celebrate your new shape without making you look dumpy and fat—even if we are! The trick is to look slim, not be thin. A lot of women just buy maxi dresses—they look so romantic. Some women I know wear jeans and short shorts--they look so damn hot! I'm not that kind, though (wish I were!). If I want to look sexy, I just bring out my mini dresses.
So just because you're going to be a mom doesn't mean you cease to be a woman. After all, you got pregnant because someone thought you were sexy enough to sleep with! Don't forget that sexy creature!
