Customers with good jobs have better stats, allowing them to do things such as move around your store faster and buy more clothes. Customers change jobs when you successfully coordinate an outfit for a customer or when they try on certain clothes in a fitting room (Unlock: Fitting Room column in the below table). Some jobs are special and only unlock when you recruit certain customers.
