Hey Alexia, I think that definitely Chanel and Fendi with Karl Lagerfeld are the ones for which you can identify the style the most easily. These brands breath of Karl's style and taste, since so many years now. I think that it will be hard for any other designer to take up the artistic direction of these horses after him. He incarnates them so much.
Virgil Abloh with Off white and Kanye's brand also has a very recognizable style. I like it however would not necessarily wear it.
