She can also randomly switch into it from a different grapple too, that's how I got it.Let Violet take over, there's a certain type of Violet pose where she is riding on your back, using your hands and legs, but leaving your torso free. Just keep struggling her off until you get the right takeover. It's gonna be when she's a companion, not as a suit
V for victory afterwards was great, and I am really liking what she and Nox are doing with reverse wearing.
