以貌取人以貌娶人
[yĭ mào qŭ rén yĭ mào qŭ rén]
The phrase combines two idioms, both of which literally translate to judging by appearances: 'judging people based on their looks,' suggesting superficial judgment, and 'marrying someone based on their appearance,' implying choosing a partner for their looks. It highlights an obsession with appearances.
