Are bare shoulders inappropriate for a therapist?

I had an online therapy session and my therapist was wearing a strapless shirt that exposed her shoulders. Isn’t that an unprofessional work attire?

Edit: I’m only asking because where I live revealing clothes are a no no and I told her that I get distracted by women a lot because I’m attracted.

You guys are right there isn’t anything wrong with shoulders. I think her choice of clothes are to get me out of my comfort zone I guess? I’ll never know
