We Happy Few by Imogen Stubbs - 2004

A stage play written by Imogen Stubbs, which was premiered in 2004 at Gielgud Theatre in London.
In the main roles: Juliet Stevenson, Patsy Palmer, Kate o'Mara, Marcia Warren and Emma Darwall-Smith.

Unfortunately, I couldn’t find a video of the event, but several pictures show that the actresses are wearing a full set of tailcoats, with top hat, white gloves and a cane.
