Lots of bounces and soft lights. I've seen David Sandberg use really cheap $5 Ikea hanging paper lanterns then stick a headlamp or a small clip light inside to get a really nice soft light. A few of those around the room might give you that soft lighting. And they weigh nothing you can hang them anywhere and easily move them to camera for each shot.
That and a white sheet on the floor to bounce some shadows away could potentially give you that look?
An expert might be able to weigh in with better info, but without being there it's going to be trial and error and just play around with it on the day. But those soft lights will be fun to work with and again, super cheap.
Best of luck. Hope this helps.Back to Lighting...
