What does "本人と似て" mean?


In this sentence I don't understand the beginning "どうせ 本人と似て軽薄でキラキラしただけの---"
For me it's : Anyway, they look alike, brilliant and frivolous But I'm not
sure. Could someone please help me ?

And if someone could explain to me the meaning of だけの in the end of sentence,
does it have the same meaning as "だけ" or does it mean something else.

  * 本人: "the person themself", "that person" (if the whole sentence is about the teacher, this 本人 perhaps refers to the student.)
  * と: a particle that marks a comparison target. See [this](https://japanese.stackexchange.com/a/52564/5010) and [this](https://japanese.stackexchange.com/a/57077/5010).
  * 似て: the te-form of 似る ("to resemble", "to become similar")

The verb 似る takes both に and と. ～に似る and ～と似る are interchangeable, but maybe
the latter is slightly more colloquial. So 本人と似て is "being like that person"
or "similarly to him/her".

  * 軽薄で: "frivolous (and)"
  * キラキラしただけ: Literally "merely shining" or "only flashy". In this case it describes how someone looks fabulous but has no substance (cf. [チャラい](https://japanese.stackexchange.com/q/5094/5010)).
  * の: the noun linking particle

This type of の does not usually come at the end of the sentence. It's an
incomplete sentence ("frivolous and superficial..."), and it probably modifies
a person mentioned in a adjacent balloon. Maybe 情夫? I need more context.
