Was there a toilet bowl or dish for the ladies in crinolines to put under their dresses when out visiting the theatre to urinate in?

Yes, during the Victorian era, women in crinolines often used portable chamber pots, sometimes referred to as "ladies' urinals," when visiting places like the theatre. These discreet containers were designed to be placed under their skirts for convenience, as the elaborate dresses made it difficult to access traditional restrooms. While not commonly discussed, such items were a practical solution for managing bodily needs in public settings.
