I don't think any comments mentioning body are appropriate in a naturalist setting. You didn't mean to comment on her body so why didn't you say "I like your tattoos" why did you refer to her body?
Soft asshole for that, but she is also a soft asshole for ignoring you after you explained your intention. Though I don't blame her, it could easily be made up on your part, she has no way of knowing which comment is genuine from you.
If she felt so uncomfortable that she had to get Y to confront you, why would she feel comfortable enough with you to have a conversation afterwards. Very strange imo. I wonder if she did believe you but once Y got involved she lost control of the situation and is not able/willing to confront Y.
Most famous one I have in recent memory was Sherry Pie, lied to a bunch of young gay men saying he was auditioning for something and coerced them into recording themselves doing sexual actions.
Not the worst thing in the world but still is a pretty awful thing to do to others
Edit; probably important to note that he did this out of drag, his drag persona was not involved at all (iirc)
