Sally Bretton

S3, Ep.6 (body double?)

Towards the close of this episode, Lucy (Ms Bretton) is giving a speech. Her dress is "very clingy", so she's not wearing knickers. As she steps out from behind the podium, she's caught in the spotlight and the dress goes transparent. We only see it from the back, which should surely mean she's in silhouette, but instead we clearly see her bottom through the material. It's a very nice posterior, but her face isn't in the same shot, so it might well be a body double (although rear nudity isn't all that taboo for actors of her generation).
