Dress Code

I don't see what the big issue is, in a retail aspect. Your job as an employee probably has some basis around pleasing the customer, but how is a customer going to be able to approach you if they can't distinguish between you and another customer. Outside of retail, in a higher more powerful job, that might be a bit much. However, when you're working a minimum wage job and you as an employee are highly replaceable wearing a uniform shouldn't be an issue.
