Most of Berry's pregger looks were first-rate, but she missed the mark here. Too much information in the bust area and a hairstyle that looks more like an afterthought add up to an overall look that lacks taste. Remember, the same rules for coordinating a look still apply when you're expecting.

The reality is that when you're shaped like Humpty Dumpty, you have to take more care when dressing for situations where you need to be taken seriously. Black is the hands-down choice. You can't go wrong. Jolie could command any conference table in this look. Keep your hairstyle and makeup understated and flattering ... just like you do when you aren't pregnant.

It looks like Spelling may have forgotten that she was expecting a baby, not impersonating one. It's important to edit and tone down your choices a bit when you're pregnant. Outrageous looks that can (maybe) work when you're slim become comical when you've got a baby bump. This look has too much of everything: too much hairstyling, too many patterns, too many details in the blouse.

Anyone who's been pregnant knows that at times a girl can feel really really tired. Take a cue from Jessica Alba and utilize color to brighten your look. This eggplant gown maximizes Alba's baby glow, and its strapless design shows off tanned shoulders. Bronzer and warm neutral makeup give the eyes sparkle.

Aguilera wore a lot of great looks while she was preggers, but this wasn't one of them. Here again is an example of why you need to edit and tone down while pregnant. Where to look first? Her blouse that's ill-fitted across the bust with its baby-doll sleeves? Or her over-worked, Whatever-Happened-to-Baby-Jane hairstyle? One or the other needs to go.
