Yeah, maybe "pretext" wasn't an accurate word. Hair in Poser is notoriously hard to manage, and I had a number of abortive tries over the years at doing Poser scenes where the victim had long hair. The hair ended up taking more time than all of the rest of the scene combined, and then the results looked wrong. I needed a short hair style that didn't reach the shoulders and preferably would move along with the head and neck. And I tried a lot of them before I finally settled on that bun.
The other one that worked ok is the hair that I used for Lucilla, the girl sentenced to be crucified twelve times. It has so many morphs that you can pose it in all kinds of ways, and it's short enough that you don't have to worry about it passing through the shoulders and such.
And yes, whipping is more than a pretext for putting her hair up out of the way. It's a perfectly logical reason and could be a chilling prelude for the victim, knowing why her hair is being put up like that and what's coming next.
Yes, and a good "chilling prelude" has more impact on the mind, in many ways, than what comes after.
