I would Import the Clothing Objects and Scale to cover the Prop, then use the Cloth Room to create a Simulation for the Props by Scaling down to fit the Prop Figure. This may require you to set the Figure up in the T Position initially, if the Pose you created is severe, then over several Frames, reposition the Props to the desired Pose.

It may be easier to create a Rigged Figure out of your Prop Figure to Pose. (Sad when Rigging is thought to be Easier)
