Although many people will come into the thread and say they get jobs without suits, let's look at the possibilities. Obviously this scenario assumes an office or formal job where most other candidates are likely to wear a suit.
Candidate is good. Wears a suit. Gets the job.
Candidate is good. Wears a suit. Doesn't get the job (another candidate better).
Candidate is good. Doesn't wear a suit. Gets the job anyway (other suited candidates not as good).
Candidate is good. Doesn't wear a suit. Doesn't get the job because of it.
Candidate is poor. Wears a suit. Doesn't get the job.
Candidate is poor. Doesn't wer a suit. Doesn't get the job
Of the 4 scenarios in green where the candidate is good enough to get the job you can reduce your chances of success by not wearing one. Why would you deliberately want to reduce your chances?
