Years ago I taught in a college when there were job interviews during a heatwave and there was no air con. The candidates were contacted to say that in the circumstances, the formal dress code of suit and tie and its female equivalent were not expected.
One male candidate rocked up with a shirt unbuttoned and spread open to not-quite navel and sported a massive chain and medallion in his chest hair. He did not get the job, though not for that reason.
Good luck with the interview, @bluewanda.
