Jouannet was known to only occasionally resort to street level prostitution. She had married her husband—who had previously been a client of hers—in November 1935, and is known to have remarked to other West End prostitutes that she would only resort to selling sexual favours on occasions when she needed "a few extra shillings" to supplement the money given to her by her elderly husband, who managed a hotel in Sloane Square. She would engage in prostitution when her husband slept overnight at the hotel, as his employment frequently required him to do.
