Help me find this!

UPDATE: I found it! As some of you suggested, it was NOT a name brand Barbie. It was, instead, a Jody Doll from 1975!

Hello Reddit! I am coming to you because I've been told that Reddit can find anything.

I am trying to surprise my mom for her birthday with a Barbie she longed for as a child. The problem is, I don't know which one it is. She has given me very little to go off of (when I slyly asked without hinting anything): a Barbie with long long hair, and a brown "smock" dress. This probably came out in the 70s or 80s (she was born in 68). That's all I got.

My internet searching has come up unfruitful, and I'm hoping that you all can help. I believe in you all! Thank you in advance!
