Superstars as

the designer's right-hand man, that's how many big fashion houses distinguish themselves.

Stars always come to the shows anyway, for example to Dior: there was a lot of screeching, because it was about the pop star Cha Eun-woo from the K-pop band Astro.

The designers who let celebrities help to go one step further.

Perhaps the most beautiful appearance as herself this year was Cher: the pop icon collaborated with Olivier Rousteing on the latest Balmain collection.

The whole thing became a single show of superlatives: A huge stadium, oversized screens, a show finale in which only black models floated down the catwalk, along with the appropriate song lines: "And when a child is born into this world / It has no concept / Of the tone the skin it's living in." Then the big bang: Cher is here!

She and Rousteing walked arm in arm down the catwalk and were celebrated: the pop star and the pop designer (photo).

A moment not meant for fashion critics, but for the masses.
