I just had two of three jobs interviews, for a vet's office reception position. I dressed super nice for these. The third and final interview is a "working interview" where I basically sit at the front and watch what the reception people do. The reception apparel seems to be khakis and a polo. I'm probably going to dress more casual for this interview, but I only have khaki capris. Would it be acceptable to wear capris? I'd be wearing a oxford on top, if that helps balance out.
