Interesting find of an objet trouvé!
Thanks Akira.
The works of art is based on the dresses of the Order of the Visitation of Holy Mary in the abbey near by.
Founded in 1610 in Annecy, France, by Saint Francis de Sales and Saint Jane Frances de Chantal.
Originally meant to offer religious life to women, widows, and those who were not strong enough for the strict austerities of older orders. They are devoted to prayer, humility, and gentleness. In Tilburg they were devoted to give education to the poor (founding the first schools) and taking care of the patients (founding the first hospitals)
