That works best when it takes place within the realm of art - if catwalk presentations were a piece of performance art, ahead of anything else.
But Prada shows are part of a giant commercial circus that's all about making profit underpinning the notion that you're intellectual for... buying bags with a recognisable logo and the newest perfume. Because that's the Prada experience for most people.
Some brands sell sex appeal or the stereotypical essence of a particular country, Prada has just decided to sell 'intellectualism' because they had to find their own furrow, and differentiate themselves from other existing brands, but it doesn't necessarily follow that they are doing anything deep.
It's the fashion equivalent of people taking photos of themselves owning a lot of books, it doesn't mean they've read and understood them. Just because you buy Prada doesn't mean you're using your brain in a different way to the non-Prada plebs, it just means you're trying to signal to the world that you're smarter because of your choice of shoe or handbag. Buying Prada is easier (and a lot more visible) than getting a PhD. The considerations that lead to Prada are still very superficial choices.
Although I'm saying this while being aware of all the tangents we could go on, about consideration of appearances.
