Duke Charles gave Slottsberg the honorary title "Överfataburshustru" - the title "Fataburshustru" was the title for the Mistress of the Royal Linen and Textiles and a non-aristocratic court office, but Slottsberg was called "Chief Fataburshustru" ('Överfataburshustru') and in practice had nothing to with the actual office. In 1795, Duke Charles further more allowed Charlotte Slottsberg to use a carriage of a design normally reserved for noblewomen introduced at the royal court - a carriage with seven glass windows - manned by guards in the livery of the Duke. This created a scandal and widespread dislike at court, voiced by the duchess, which caused the regent Duke Charles to see a need to make his relationship with Slottsberg less visible, he stopped allowing her to use this type of a carriage and drivers with his ducal livery.
