It’s a very old tradition to celebrate spring by dressing up for Easter. The new hat or “Easter bonnet” was an important part of the spring costume in the days when hats were more in fashion than they are today. The Cave Creek Museum is featuring mid-20th Century hats from its collection, as Artifacts of the Month for April 2014.
“In your Easter bonnet,
With all the frills upon it,
You’ll be the grandest lady
In the Easter Parade.”
“Easter Parade,” Irving Berlin, 1933
