The exhibition is articulated according to the criterion of the occasions and circumstances that mark daily life: gala dresses and festivities, everyday clothes, ritual dresses used during processions, nineteenth-century midday dresses and mourning dresses, expertly sewn by Mrs. Teresa Sorrentino Marcigliano, an art that she learned from the teachers Luigia Forte Sorrentino and Teresa Amen in all the meticulous ways of execution of each garment, differentiated by occasion. The exhibition reproduces thirteen dresses of local costume, arranged in three showcases, worn by as many mannequins, highlighting their peculiarities.
