Searching for non-profit that provides work attire

Hi everyone! I just recently got a restaurant job that requires us to wear non slip shoes and black slacks. I was wondering if you all know of any organizations that would give those items for free. I know organizations like Dress for Success cater to those going into corporate professions, so I was wondering if there are any organizations that help individuals going into the service industry.

Thank you all in advance for your answers!
