binary oppositions

They are sort of opposites but not  all the time, they are meant to oppose each other.

A sexy person is seen as the better of the two
binary oppositions. 'Everybody' loves
them and wants to be them. They get
what they want and live the life others would
love to have with lots of money.

An 'ugly' person is seen as the worse of the two.
Nobody wants to be seen as ugly. They
generally have low self esteem and do not have
the confidence to talk to the people they may
fancy. People often change the way they are to be 'sexy'.
