Where does "I don't look like a prince in a dragon robe" come from?

"I am not like a prince in a dragon robe" may be a taboo in ancient language! Anyway, as long as you fuck the emperor or something, you'll be easily beheaded! Wearing a dragon robe is not like a prince. The implication is that you were born as a prince, but not like a prince. Even if you wear a dragon robe, that's it.

In life, I often hear people say that some people don't look like princes in dragon robes.

The implication is that he was born a prince, but he doesn't look like a prince, even if he wears a dragon robe.

But in reality, it's not that the prince looks like a dragon robe, but that he is not a prince, but he must also wear a dragon robe to show off as if he were really a prince.

General rule: People's taste is not displayed by their beautiful appearance (gfd), but determined by their inner cultivation and temperament. So "some people" don't look like princes, because they don't have the temperament and cultivation of princes (heirs to the throne), even if they wear dragon robes (special clothes for emperors).
