Why do some people think they are beautiful just by looking at their backs?

Some people feel beautiful when they see the back, probably because they are attracted by some features on the back. For example, a person's back may show a slim figure, graceful curves and smooth lines, which are usually considered beautiful. In addition, some people may have some preconceived ideas, for example, they may think that women with long hair are beautiful in the back, or people wearing certain clothes are beautiful in the back.

But it is unfair to evaluate a person's appearance only by his back, because everyone's figure proportion, lines and clothes are different, and his back can't fully reflect a person's facial features and personality characteristics. Therefore, we should try to avoid judging a person's appearance from behind, but look at a person's appearance and personality comprehensively.
