Answer
Two Marian scapulars were approved by Pope Leo XIII: the Brown Scapular of Our Lady of Mount Carmel and the White Scapular of the Immaculate Heart of Mary. The Brown Scapular is associated with the Carmelite Order and is believed to offer protection from the fires of hell, while the White Scapular is associated with the Marianist Order and is believed to promote devotion to the Immaculate Heart of Mary.
