If attractiveness is subjective then why do most people tend to agree on what is attractive?

I already hear the responses now. The minute 10 people agree somebody is attractive you're always going to have some contrary and pop up and say they're not attractive at all. I get we all have preferences that define us. But why do so many people deny that attractiveness is LARGELY objective? I mean we have models for a reason. Because society as whole agree mainly on what they deem as attractive and unattractive.
