MVVM/WPF: Using a ObservableCollection<T> as a list in a domain model, is that good/bad ?

I have aggregated models like Customer:Order:Product.

As my View is bound to the BillingViewModel which has a Property Customers of type ObservableCollection

and ONE customer in this collection has a "list" of orders named ObservableCollection

and ONE order in this collection has a "list" of products named ObservableCollection

Well I need the ObservableCollection`s for databinding but should a domain model really have a ObservableCollection ? normally it has a

List or IEnumerable !

Is this bad habit or having side effects?
