Did you not just read what I posted? I am shrink wrapping the dress to the figure, not the other way around. Go back and read what I said.

Here Is the dress NOT parented to the body. Started with the figure at 100% on frame 1 and ended with the figure ZScaled to 150 at frame 30. As the figure grows into the dress it effectively shrink wraps. If it had been parented to the figure like my first example it wouldn't have shrink wrapped as the figure scaled out.

Somebody else in the thread has already pointed out to you that you are doing the exact opposite of what I do to get the same effect. Regardless, props scale with the figure when you parent them.
