Some form of an English peers’ robe may originate back to the end of the 14th century. The ceremonial robes made of crimson silk velvet, trimmed with white ermine & rows of black sealskin spots date back at least to 1614. It looks like the robes below have 3 rows of spots, or perhaps 2 1/2 rows. That would mean that the robes belong to an Earl or perhaps a Viscount. A Baron would only have 2 rows of spots, while a Duke would rate 4 full rows.
