[All] If you wear a kindergarten uniform to school, is it an expensive kindergarten?

The members of TUBATU are gathered together and talking about their childhood.

One of the members said that he woke up in the morning and went to kindergarten wearing casual clothes.

They say Yeonjun didn't wear casual clothes but instead wore a uniform.

I also bought and wore a kindergarten uniform when I was going to kindergarten, but I was surprised when I heard that Yeonjun went to an expensive kindergarten.
