I want to say most likely plaid bc of the school girl vibe and I remember plaid being everywhere during that time. But tbh I can’t say for sure. Memory is a funny thing. The truth is most people don’t pay that much attn to detail and we fill in the blanks a lot of the times.

The only one I’m def sus about is berenstein bear. First off I knew nothing about Jewish last names or anything about that as I was a fucking kid but I still read it as “stein”. But Berenstain? I don’t know a lot of “stain” suffixes. Maybe I’m just uninformed.
