Very rare these days to find such a stunning example from this time; usually they have oxidized a little giving them a yellow tint. This one was owned by someone who knew how to look after it to prevent that (I can tell you if you are interested in buying). The sleeves are full pelt,  deep and luxurious. This coat still has its blue sheen, with beautiful darker parts.  
A real bedroom/rock chick coat these were the must haves for the glamour set. You do have to watch Dynasty to have an attitude..... simply sensational decadence.
