That girl was lucky she was only humiliated by the ghost and not outright killed on the spot like others. Maybe a silver lining for her is that the audience is already way too terrified to actually care about her ruined dress and exposed breasts... and then she starts ripping her dress even more, I guess she's decided on stripping as her competition strategy. Whether she's doing this to make the best of a bad hand of cards or an act of madness brought by fear, I don't even know.
Perhaps sales must not be doing so well by now for the fanservice to come rolling back in when we're supposed to be in the thick of the plot. This was a chapter light in substance and has a bit more of the other plot than I expected.
