I like this "business model" though. It's a very smart merchandising trick.
The couture collection acts as an extravagant and experimental prelude to the ready-to-wear collection. It gets a physical runway show and an accompanying film, which allows it to be seen by lot of people, who could eventually buy the ready-to-wear collection.
The ready-to-wear collection is a more approachable and accessible version of the couture collection. It only gets a lookbook, which saves money. The sales of the ready-to-wear collection finances the whole operation.
Lots of the designers on the couture schedule could benefit from this sort of operation as it "democratises" the couture collection, saves money on marketing and alleviates the pressure of having to offer four completely unique runway collections a year.
Also, yes those dirty sneakers need to go.
