I know this this a silly question, but I thought it was worth asking.

Stanford GSB is having an admissions event in my area, and I am actually confused as to what I am supposed to wear. It isn't an interview, just an info session. I work in the tech industry, so jeans and a shirt work well for me, and when I get really fancy I wear jeans and a blazer... but that is usually the extent of me dressing up.

Should I be formal for this?
