Dating era of this cellophane hat?

[CarlyAnn]

I just began collecting vintage hats and I found this one this morning, I'm unsure of the era. Any info would be appreciated thanks!

Hello,

I would place it in the very early 1960s. How wonderful to know you will be a hat collector, and I wish you great success in finding more treasures.
