Maternity pic outfit ideas?

Elizabeth
I'm getting my maternity pics done November 21st. I know it's a few weeks away. But just wanted to start getting an idea of what to wear for them! I live in the St. Louis Missouri area, so the weather here is not consistent. Every maternity photo I see the girl is in a maxi dress. But I don't want to get cold, as these pics will be taken outside within an hour and a half from sunset. I know I'll wear jeans and high boots with a grey sweater for one outfit, but what for another? Any suggestions? Especially with accessories? Little baby shoes for the pics? Ah!
