What music did fashion shows play pre-rock?

Since the early 60’s there’s been a tight connection between the world or high fashion and rock, especially Europop and techno. But what did they play, if anything, back in the old Coco Channel, Christian Dior days? European Jazz like Nino Rota? Candelabra music?

I think fashion shows in the old days didn’t have a catwalk in quite the same sense, and it was of a dull presentation with classical music and lots of jazzy stuff like this.
