Rob Halford Red & Black Velvet Robe.
These were made around the ‘Sad Wings Of Destiny’ era. This will have been around 1975/76. They were made by a girl called Fid who lived in the Chelsea area of London. Rob can be seen wearing the Black Robe on the back of the Sad Wings of Destiny album.
Also worn during a 1975 Whislte Test session
And here is a link to that session – can’t embed – sorry
