Here is a shower cap. Not really a hair net and it comes with it's own hair that sticks out. I assume you could edited the hair out in the mat room and then with a net texture, make a somewhat reasonable hairnet. It loads as a Hair prop. So you can scale and trans to fit any character or V4 as you desire.
