Help (Please :-) Dating a Koret Handbag

[Freyasmews]

Hi lovely humans! Do any of you have the vaguest inkling as to when the Koret bag shown (see images below) might have been manufactured? I found it at a thrift store a while back and am trying to find out more about it.

Thank you, thank you, thank you for any light you can shed!

It looks 60s to me. Nice thrift store find!

Thank you! What makes you think '60s? (Just for the sake of my education--I know nothing about how to date Koret handbags.)
