Did anyone hear of the concept naval birshus HaTorah? This is an exact example.
I agree (as I did earlier, assuming it is similar to dancing with a pole). However, don’t say the word “Assur” in connection with this (granted you did not, but others did).
Edit: To add, this has nothing to do with women, and really not much to do with Tznius the way the term is usually used. IMHO (and others will disagree) yidden should not glorify their sexuality in public, even before the same gender. It is not “Tzanuah”.
