Question to all: Under a suit, for a job interview, do you HAVE to wear a typical button-down blouse (collar over the suit and all). I saw some cute shells today while shopping (I've attached one I actually bought), but was wondering what everyone thought. Maybe wear the typical button down in a "safe" color for the interview, and save the shells for the work-place? I am in the science field, so I apply mainly for laboratory/testing (supervisory) positions (I'm 27, if that helps!).
