DS still young and living at home has struggled finding a job that's not warehouse work. Finally got a job but its minimum wage etc. He doesn't have a uniform but is supposed to wear certain colours. Fair enough but he's struggling to get straight and I think if an employer is so particular about a uniform they should either provide it or help you buy it
I suppose it depends on the clothing request for instance if it was in hospitality and staff were required to wear black trousers and a white shirt then this I think would be reasonable. Most people have to buy work clothes unless there is a specific uniform.
