Just a quick note for those interested in the matter of vestments and what might be expected as regards the character of the upcoming papal liturgies in the USA (at least as regards the Pope himself) and how that might tie into the pontiff's evident programme of working to re-enchant the liturgy, bringing beauty and solemnity back to the fore again.
A New York Times article yesterday noted that "...three Polish nuns have dusted off a gold and silver garment, hand-woven more than a century ago, for the pontiff to wear at the Basilica of the National Shrine of the Immaculate Conception in the capital."
This will be sung vespers, therefore the vestment they are speaking of will be a historic cope from that basilica.
