Hello! Please help with dating this Hawaiian Shirt

[Caleb Phillips]

Hi! This is my first time posting on here! I recently acquired this shirt and want to list it but just want to make sure I have the correct decade. Any help or information about the label/time frame would be great.
Thank you

Looks 70s to me. What is the RN number on the label?

I also get a 70s vibe.

Yes, 1970s with the collar and buttons

Thank you all! I figured 70s but sometimes I mix up the 50s pieces too since the collars are kind of similar (but i think the 50s collars arent quite as large)
The RN number is #45260
