Having worked part time in retail when my son was little, what you’re describing is standard practice in most, if not all clothing retail jobs. You’re required to wear the brand’s clothing but you get it at a discounted rate. Never free. You’re also expected to arrive half an hour before opening and stay until you’ve finished the cleaning and tidying after the shop’s shut but you only get paid for opening hours, usually at minimum wage. We were even expected to do tasks such as washing the outside windows and facade. However, I’m talking about a fair few years ago. People used to just get on with stuff. These days, everyone is outraged or ‘shamed’ or whatever. You can see why people refer to Millennial/younger generations as snowflakes.
