That's simultaneously the best explanation and also the dumbest reasoning. If a girl wants to model nude, she'll do it and it's not down to the country, her team or whatever, but once she decides not to do it, it doesn't matter how easy it'd be and what she's done before.
If you ask me I think that's the reason she just doesn't enjoy it anymore either because people kept calling her a "loli" or she just got burned out from it or maybe the shit in Ukraine really fucked with her mental state and she just wanted to wash her hands of it for whatever reason who knows? Either way she making that bread regardless personally I'd like to think she'll return to nude modeling eventually even if not fully like she use to and just drops a nude set here and there. But if it is a persona thing then maybe she's just closed that chapter of her life.
