Hi David, I apologize for the delay in answering your comment, some notifications tend to fail.
Yes, you are right, she is very flexible. I suspect that she is Ulyana Lopatkina, former principal dancer of the Marinsky Ballet and cast partner of the former dancer and current photographer Alexander Gouliaev, but I am not absolutely sure, that is why I am not mentioning her name.
Thank you for your comment, have a nice weekend!

Hi Gus, I am sure this is Ulyana, she is 1.80 meters tall. The length of her legs, arms and torso indicate this.
