I have never been a fashionista. So when my granddaughter Taylor, 5, told me that Fancy Nancy was her favorite book series, I had to know more.

“I like her because, you know, she’s Fancy,” said Taylor. She wears lots of things.” And indeed she does. In her books she flaunts baubles and boas and bows – all things Taylor loves to dress up in herself.

We had the full Fancy Nancy immersion experience Sunday when Taylor and I attended “Fancy Nancy The Musical,” which played to a packed audience of fancy little girls and their moms or grandmas at our local children’s theater.

So why is all this fanciness so popular? According to Jane O’Connor, who has now authored 56 Fancy Nancy books, dressing up does for girls what a Superman cape does for boys: makes them feel powerful.

Maybe I should try it.
