Grace and Lydia have lots of clothes, lots of shoes and certainly plenty of outerwear. But apparently nothing they have is as cool as it is to dress up as Mom and Dad. So they take our clothes and add it to their already large wardrobes.
So not only do they dress the roles of mom and dad, but then they act it out too. They pretend to be madly in love and talk about going on dates with each other.
She does look darn cute though.
