It hadn't even occurred to me to wear clothes in pregnancy pictures.

Did I then take that movie meeting, all unprepared, after dressing in a way to accentuate my pregnancy, then to downplay it, then changing outfits again to accentuate it?

As you try things on, remember that you need clothes for the size you are now, the size you'll be at nine months and even for the size you'll be for a couple of months after delivery.
