Oh I don't know... I think a lovely shot of me and several of my friends skipping along a beach in g-strings with a charming boat, or maybe a snake photoshopped in would be the perfect pic to greet guests as they walk in the door.
Very, uh, dynamic indeed.
In all seriousness - no, I wouldn't do a lingerie pregnancy shot. It might work for some people, but I'd just look ghastly.
