When I visited the Prinknash exhibition I was taken by a very fine Arts and Crafts High Mass set of black vestments. They were referred to as The Gerontius Vestments though no one really seemed to know why; which is annoying as that is one of my favourite pieces of music. They featured embroidered panels with suppliant figures and angels. I was amused to note that at least one of the tailors dummies upon which they were displayed was obviously female. One of the monks explained that he had great difficulty dissuading one visitor of her belief that they were for the celebration of the Black Mass. He felt it was quite clear when the notice described them as " Black High Mass Vestment Set".
That isn't the vestment in the pic btw.
