How can I implement cancelation of editing an object using MVVM.

For example: I have a list of customers. I choose one customer an click the button "Edit", a dialog window(DataContext is binded to CustomerViewModel) opens and I start editing customer's fields. And then I decide to cancel editing, but the fields of the customer have been already changed, so how can I return a customer to its previous state in MVVM?
