WCIF: 70s/80s Leisure Suit with Long Collar

Hi! I've been looking a while for a 70s/80s Leisure Suit with the long collar like the one John Travolta wore in Saturday Night Fever. Here are some examples - 



I don't have any specifics, only that it's a blazer with a long collar.


Thanks in advance for any help! :-)
