Double standard?

I recently had to have some surgery. Of course, for the surgery, I had to put on a hospital gown with nothing underneath. Before the surgery, with my IV already in, the (female) nurse escorted me to the restroom. As she was settling me back into bed, she asked, "Where do you swim?" Now, I had mentioned swimming, the only way she could have known I swim regularly was my Speedo tan line. I told her where I swam, and we talked a little about swimming. I thought it was nice of her to ask.

However, when I got home, I thought, what if a male nurse commented on a woman's tan line?

Your opinion: Nice to notice or unprofessional?

FYI, there is a Speedo group on Lush.

A tad unprofessional but hardly the worst possible offence. Still, if it was a pattern or seemed to be escalating beyond just commenting on their tan lines, I would hope word would reach their supervisor and that a discussion about appropriate guardrails would be had. I am pretty sure that would be the case for the respiratory therapists (also a regulated health professional) my employer has working in the community.
