The answer is no, celebrities generally do not pay for their Met Gala looks.
The Met Gala is a high-profile event where designers lend their most elaborate creations to celebrities, hoping to gain publicity and boost their brand.
These designer gowns are often considered investments for the brands, as they can generate significant media attention and increase demand for their products.
In exchange for wearing the designer's creations, celebrities receive free access to the event, free styling, and often, free jewelry and accessories to complete the look.
While some celebrities may choose to wear their own personal clothing, this is rare, as the Met Gala is an opportunity for designers to showcase their most extravagant designs.
However, it is important to note that some celebrities may contribute to the cost of their looks in other ways, such as by agreeing to participate in promotional activities for the designer.
Ultimately, the Met Gala is a collaborative effort between designers and celebrities, with both parties benefiting from the exposure and prestige associated with the event.
