Maternity Photos help please!!!

alicia
Hello, I'm thinking about doing a professional maternity shoot or grab my mom professional camera when she flys in.
I have a few questions. I'm not sure do it an inside or out door shoot by the beach or a garden.
Also where would I get the growns that show off your belly?
 I'm open for any recommendations or suggestion.
Please post any of your photos for some inspiration ideas.
This is all new to me.
Thank you
