So I've gone and had a look. First she wore a nude top. Yesterday she didn't. She was not in a bodysuit either. She wasn't in a pair of tights and has some kind of nude thing tied around her ribs, a rolled down/cut top perhaps? But her breasts are not covered, except by the cushion.
In terms of her having the resources to leave, according to the DM her family and friends can't contact her because he's put up a wall around her blocking everybody. Not, you or I can't do that so easily, but it's not hard to imagine how someone with his resources could. And there's no way her resources matched his when they met. She didn't have a team around her either. KK had a very large and strong network as well as strong financial resources.
There are photos of her a few months ago in revealing bodysuits with a big grin on her face, relaxed body language, bright eyes. If she's able to pull off the scared woman look, with hollow eyes, then this woman needs an Oscar, because not many actors do it so well.
I think before anybody comments about it being "her choice" they need to do a deep dive on coercive control, what it is, how it feels and how it typically manifests in patterns of behaviour change. They may still think it's her choice, but at least then it would be from an informed position.
Just on the surface of it alone, it would be a huge coincidence if a man who is known for being controlling in relationships got into a relationship in which it appeared like he was deeply controlling, but actually it was just her pretending to be embarrassed and humiliated in public. Not impossible, but the chances are rather slim.
