Dressing etiquette for interviews in academia
I have been invited for a PhD interview day at an institution in the US. I was just wondering how formal/informal these interview days are. I know I will be meeting a few professors for which I have expressed interest. I definitely do not want to be underdressed but also I do not want to overdoit. Especially because I have noticed in my field ecology/biology the dress code is quite loose. (I remember this colleague of mine that would come to work with a shirt full of paint stains because he was painting his house, that cracked me up every time)
Would nice pants, a buttoned shirt, and elegant black sneakers be good enough? Should I wear a blazer as well?
