Ask her, period.
Tell her you think it would be sexy and you want to watch her.
If she won't, is offended, thinks it's stupid, thinks it degrades her, then that's it. End of story.
It's really up to her.
The idea isn't to "Make" her strip, as you put it. The idea is that she's supposed to enjoy turning you on by using her body for you. If she doesn't enjoy that, you've got bigger problems.
