Following the sunnah and being put down by family

A man’s been trying hard for a job for sometime. He attends interviews with his kurta, adamantly maintaining that success lies in following the dress of Nabi Sallallahu Alayhi Wasallam, even if that means he has to go hungry, yet his spouse & family implicate that he is affecting his chances of obtaining a job because of the impression it creates. What advice would you tender to assist the man in this case & give him strength from the inevitable doubts created in his mind by his family?
