Falda

The Falda is a particular Papal vestment which forms a long skirt extending beneath the hem of the Alb.When it is worn, the skirts of the Falda are so long that the Pope needs train-bearers both in front and in back whenever he walks. It was used when the Pope celebrated Mass.^[1] This form of vestment has its origins in the 15th century and earlier. It is initially made of cream coloured silk and worn over the alb and under the Chasuble or Cope. It can be used in papal funerals where it was draped over the Papal body when it was in state. It has, since the Pontificate of Paul VI, fallen into disuse.
