Hi,
I am so excited by the possibility of finding this book remembered so fondly from my childhood!
What I remember is a children’s book (maybe ages 3-7) about a little girl, maybe born as a baby, who grew and grew grew, so fast or so big, that no clothing would do. So (her mother?) dressed her in clothing made of vines and flowers which then grew with her as she grew. Covering her as she got taller and bigger, growing as she grew.
I remember the book being very colorfully illustrated. Flowers, vines, perhaps she had long hair. I think the illustrations may have filled the pages – not been small.
I THINK the book was horizontal, rectangular in shape.
I was a young child in the mid-late 70s.
