Clothing Apparel

Is it safe to wear the apparel of a clothing store to a job interview?

I have an interview with a clothing store today and I was wondering if I should just wear their clothes to the interview, or if I should still be all spiffy.

No. Do not do this. It will look like you are assuming you will automatically get the job. If I were the interviewer, I would put you on the “do not hire list” and not call you back. Just being honest here. I have about two years experience of interviewing and I know exactly what to look for. I have also screwed up some interviews myself based on what I wore.
