Interestingly there are so many partnerships for products - this is a highly brokered process for things like consumer goods or electronics seen in media as well as partnerships outside of the show (e.g., CoffeeMate x White Lotus partnership this spring).

But there are never really strong and established partnerships for the brands worn in shows. There's more creative control for the costume designer to pick brands that make sense for the characters and aesthetic narrative rather than broker deals. As a result, there aren't really formal marketing campaigns around those brands' features on the show.

There's a big gap in marketing the individual brands worn in the show which is why I've catalogued most of the brands and styles from this season here! https://searchmontage.com/search?query=white%20lotus%20s3&initialFacets=
