What does the expression used by Dickens in Our Mutual Friend introduced himself by name and buttons mean?

In "Our Mutual Friend," the expression "introduced himself by name and buttons" refers to a character who presents himself formally and with a sense of propriety. The phrase suggests an emphasis on both identity (his name) and social status or appearance (the buttons, likely referring to his clothing). This reflects Dickens's commentary on the importance of social conventions and the ways individuals define themselves in society.
