I was a little disturbed by that pose as well.
But I blame the photog and the promotion company.
The girl is, what, 6? 8? And the adults in her life are taking photos as if she’s a full grown woman using her sex appeal to promote herself?
The photos are from a “dance” photo shoot and were not part of a model shoot. They were taken to showcase her talent as a dancer, for a dance portfolio. The photo is to display her flexibility, specifically in her back in this pose. If you have ever been to the ballet you would see ballerinas in similar poses and understand that flexibility is required to excel as a dancer. Nothing more.
To even state that a child would have sex appeal is quite appalling in itself.
I understand I am a visitor to your page, and I respect your right to do and state what you feel. I am only offering to clarify the portrait, so you may understand.
Thank you
