Clerical Costume

In the Diary of the Rev. Giles Moore, rector of Hosted Keynes, in Sussex, published in the first volume of the Sussex Archæological Collections, there is the following account of his dress:— "I went to Lewis and bought 4 yards of broad black cloth at 16*s.* the yard, and two yards and 1/2 of scarlet serge for a waistcoat, 11*s.* 1*d.*, and 1/4 of an ounce of scarlet silke, 1*s.*" and this appears to have been his regular dress. Will any of your correspondents inform me whether this scarlet serge waistcoat was commonly worn by the clergy in those times, namely, in 1671?
