So, living for a day means finally indulging your group stocking fetish? I don't get it. IMDB says:
Guinevere Pettigrew, a middle-aged London governess, finds herself unfairly dismissed from her job. An attempt to gain new employment catapults her into the glamorous world and dizzying social whirl of an American actress and singer, Delysia Lafosse.
Ugh. I liked it more when it was about stocking fetishes, and when I thought it was Kate Winslet in the poster.
