Actress Sybil Thorndike dressed as Victorian lady at rehearsals for Chelsea Arts Ball.
Full title reads: "Mrs Grundy disapproves!"
Various shots of glamorous models walking down cat walk dressed in fancy-dress costumes. Watching them is actress Dame Sybil Thorndike dressed as a severe Victorian lady - Mrs Grundy. As the girls walk past in their skimpy costumes, Sybil (as Mrs Grundy) makes lots of disapproving comments such as "The Shame!", "Oh, you hussy" and "well, in my young days if the girls had dressed like this the vicar would have given them such a look!".
The girls are rehearsing for annual Chelsea Arts Ball.
