Need Help Identifying Age of Men's Shirt

[Russel Clem]

It is a Krink-L-Kool by Enro men's shirt. My guess is 1950's. I have checked the label resources page and this is not listed. Searches of the internet come back with nothing. See attached photo. Thanks in advance for any additional information you can provide.

It looks like a pajama top to me.
50s to perhaps early 60s, most likely, I'd think.

I have a mens robe of similar puckered plisse' fabrication, and I love it.
