The vast majority of attendees to the Met Gala monetized their appearance.
From makeup to hair products to how they got ready to accessories, everything was sold at a price.
The attendees would then tell their followers how to get the products.
The powers that be have always given preference to advertisers who advertise in the magazine for a year or longer, often with multiple pages.
For a fraction of that, advertisers just throw some money at an attendee and get a lot more eyeballs. Plus the makeup artists and everyone else also get paid by advertising every product they are using on the attendee and then also giving a link to purchase.
So, because of that kind of monetization, you have the stylist people paying the attendee to work on them rather than getting a fee for doing the work.
Next year it wouldn’t shock me if a guest or two had advertising on what they choose to wear, much like NASCAR.
