It would be best to freeze them undecorated then thaw and decorate. Some cookies reach their peak around 2-3 days at room temperature (especially if the butter content is high). After that they are not as fresh. Other cookies the flavors intensify even more after 2-3 days. It really depends on the type of Cookie.
But yes, either bake the cookies and freeze them OR freeze the dough, thaw and bake THEN decorate. But don't decorate and freeze.
