Beauty lies in the eyes of the beholder

Whether too short, too tall,too skinny,too fat,too dark or fair,too old or young... Once true love exists, no matter what the world says its gonna be you guys against the world.

Beauty is subjective.  What one person loves, another loathes.

There are objective data that indicate certain elements of "beauty" may be common in some cases.  For instance, facial studies indicate that human responses to facial symmetries and self-similarities can be predicted in aggregate.  Musical interests are also studied, and the results show clusters of taste and approval.  However such studies necessarily are limited in scope; none attempts to quantify "beauty" per se, but only to describe aggregate human evaluations.  The individual responses remain subjective, variable, and unpredictable.

People decide what they like and what they do not.  We do not all decide the same way.  The choices vary among persons, across cultures, across times of life and times in history.  Individuals can always be found whose tastes are several sigma away from any mean.  So we say that "beauty" is not intrinsic to the beheld, but resides in the beholder.
