Which of the twelve constellations is the most vain?

I think it is Capricorn, which does everything only for fame and fortune, and it is also the heaviest of the twelve constellations. Even for the sake of fame and interests, you can be absolutely ruthless to anyone and anything.

Virgo, like Taurus and Capricorn, are both born and bred and materialistic, but their modesty and spirit of serving the public are unlikely to be vain. Taurus values material things, but will never betray friends, pay more attention to cheapness and practicality, and will not pursue luxury goods.

Leo has a lot of face. He is never stingy and generous to his friends. Aries and Sagittarius are also generous.

Scorpio, Cancer and Pisces pursue emotional stability more than material things.
