I would like to see redefinition of what is viewed as professional or unprofessional. I personally don't think that your choices to accessorize your body change your professional demeanor or competence in your field. I'd like to see this change, but it won't unless we challenge people to redefine their views.... so wear your nose ring! With that said... I did take out my 1/2inch plugs in my ears prior to my SUNY interview, however, the holes in my lobes were still the size of my pinky, and plainly obvious to the interviewer... and I got accepted. But, I'm sure this varies widely from place to place. I only have my undergraduate experience at Berkeley and my SUNY interview to speak of.... both very "blue" places with diverse populations and generally tolerant attitudes.
