I am not saying don't judge the therapist on whatever basis you want to judge her on.
I am saying that there are or may be reasons that people dress in a way that seems odd to others that are based on factors outside of their control. I dress like an L.L. Bean catalog lesbian ex-nun. I'm comfortable and if others think I look goofy that is something I am not going to try really to control. As my grandmother used to say it's one of the dubious benefits of getting old. When I was in law school an article came out about how to tell if your professor was an alien and a lot of it was the they dress funny, don't get cultural references and have odd syntax. These days I feel certain some of my students would immediately think of me after reading the article.

I don't generally judge a therapist on clothing because I don't notice it. I judge them on not being well read Because the woman never understood what I was talking about and if she simply read some of the classics, I believe she might have. No better way to judge them just a different one
