It’s still the same designers at the end of the day even if the visual language is very different IMO.
Nobody, except the executives of LVMH or those who are shareholders, knows.
It’s just known that they made 20 billions of sales last year.
However, through his position at the maison, his creative control and some industry whispers (even those who works for Vuitton), it’s known that it is doing well. Doing well for a house like Vuitton is not the same as doing well for Versace for example. It’s a luxury good company first but the investment they made for Nicolas paid up. He wanted them to really develop the RTW and they installed a structure that is quite similar to what he did at Balenciaga tbh.
When your bosses are happy, you can collaborate with an artist to install a weird installation, that probably only you are excited about, inside le Musée d’Orsay.
