I'm guessing that the dress showing below the quilted picker-upper jacket is not what Ange should have been wearing, (It's the dress she wore in the scene where Carolyn see's her dead in her memory, the dress Ange wore in the portrait, and was buried in[?]).
Hmmmm... indeed. Maybe Angelique's cunning disguise just isn't quite as foolproof as she thinks ;)
(let's not even get into the fact that no one in their right mind would be wearing a coat like that in the middle of June! :o)
Maybe the camara man was using the "privacy room" when the shot was being discribed.
