Summary
This quote suggests that a person, referred to as "Vice," is aware of their negative qualities or flaws, symbolized as "ugliness." In order to conceal these undesirable traits and present a more favorable image to others, Vice figuratively "puts on her mask." This implies a deliberate, deceptive act of pretending to be someone they are not, masking their true identity, intentions, or true nature with a facade. It highlights the tendency for individuals to hide their negative attributes or engage in deceptive behavior to gain acceptance or avoid judgment from others.
