I have a reference to this "song" from my small town in Michigan from about 1948. It was sung by either the high school girls Glee Club or the girls basketball team:

We are the DeWitt Girls
We wear our hair in curls
we wear our dungarees
Way up above our knees
We never smoke or drink
(That's what our mothers think)
We are the DeWitt Girls
We are the DeWitt girls
