I came across this picture of my mother, taken in the early Twenties. The fancy basket makes me think she could be dressed for a May Day celebration or perhaps she's going to be the flower girl in a wedding.
There are quite a few pictures of her in similar get ups -- the high socks, the short frock, and the exuberant bow. It must have been a fairly common look at that time.
The Oz books were of that time and Dorothy wears a similar outfit.
I grew up reading the Oz books -- borrowing them from friends, the school library, and finally, getting my own -- which I still have. Ozma of Oz is probably my favorite of them all -- the sea voyage, Billina the talking hen (with her wonderful common sense,) the trees that grow lunch pails, and the exquisite (though not very nice) Princess Langwidere (languid dear) with her wardrobe of exchangeable heads.
The books are, in my opinion, far better than the famous movie which has always seemed just plain silly to me. (Except for the Witch and her Flying Monkeys!)
Time for some re-reads!
