Vanity's Vanity is about masks we wear to project a certain image or to conform to social norms. Masks in a box, implying a collection of personas or identities that one must adopt to navigate different social situations.

The title also hints at the idea that this constant shifting of identities is ultimately futile, as it is driven by vanity and a desire to fit in rather than by authenticity. It suggests that the pursuit of external validation and the need to conform can be a never-ending cycle, much like the pursuit of vanity itself.
