The white and blue windowpane check gown Honeysuckle Weeks wears as Alice Cottisloe in "Plots and Proposals" when she answers the door is the same costume Billie Piper (Fanny Price) wears in Mansfield Park (2007), Rosamund Stephen (Henrietta Musgrove) wears in Persuasion (2007), Victoria Hopkins wears in The Regency House Party (2004), and Emma Thompson wears in Sense and Sensibility (1995). The same costume is also worn in Byron (2003) by an extra at the London party where Byron meets Annabella Milbanke.
