She is also wearing unidentified baggy blue jeans, gold earrings, and a gold bracelet.
In the promo picture above, the bracelet may not be accurate. She is wearing the wrong ring, and she isn't wearing any earrings. I wasn't able to get a clear enough screenshot of the bracelet in the actual episode to tell, so if anyone could help me out with that I would greatly appreciate it.
She is wearing the same necklace and rings as outfit #1, but different earrings. The earrings are silver triangles with a black mark in the center, and are probably the same earrings as those worn in the Caretaker. She is also wearing sheer black tights, a black tank top under the jumper, and unidentified black shorts or skirt. It is possible that the shorts are the scallop hem shorts from the Caretaker, but there is no positive proof yet. She also changed shoes into unidentified black boots, possibly the Topshop All Mine boots.
