Congratulations, Taffy! I am about to be in the same style-spot with baby #2, which is due in November.
I definitely second the vote on several of those tops that chewyspaghetti posted. Through a little too much trial and error after my first, I finally found that tops such as the lace-trimmed keyhole-neckline blouse worked very well for me. They looked polished, fasionable, and didn't have too many ruffles or gather, which reads 'pregnant', especially with a bit of a belly. When I wore tops in that shape, I always got complimented and asked if I'd lost weight (which is a good thing postpartum!).
This time around, I will be focusing on acquiring more of that style of top, since another benefit is that they continue to fit even as the bump smooths out. They have really suited my style (comfortable, loose and flexible, but polished). A cardi and scarf add further personality, layering functionality, and texture to hide baby bumps. For that matter, a well-draped scarf can go a long way for baby belly in many situations!
Keep in mind that I'm a rectangle, not a pear, so different proportions might work for you. I did find that a streamlined bottom was key with this look, but I don't have skinnies, I wore slim-fitting bootcuts and that worked well.
Also, long boyfriend cardis can be another good streamlining look, as well as woven button-front tops... though those are more pricey I found because the fit needs to be more exact, meaning you can only wear them for a limited time. A knit vest over top can extend the wear time and streamline the midsection, if the shirt fabric is not too bulky. Funk it up with unique jewelry and scarves and you are good to go!
Hope that helps!
