Dressed in a beautuful formal gown, Cynthia treats herself to a lovely bubblebath. She gets into the bath in her dress, sits down in the water, giggling as it soaks through her outfit, and then uses the shower taps plus empties a bottle of bubble bath all over her dress and then latthers it up before showering it clean again, all while she's still wearing it.
Note though Cynthia has glorious waist-length red hair, she largely keeps it dry in this scene, though she does show it off and it gets a bit splashed.
