Vintage Hat Identification Help

Hi! I have had this gorgeous turban-esque Union Made hat for years. I've always wanted to wear it but never known how and no one I've known knows how. I've tried googling, but I've never seen anything like it in my shallow searches. I was wondering if anyone here could help me.

 

The labels and split in the band, always goes in the back

 

It is a bit hard to describe exactly how this is worn. Off the face, perhaps showing a little hair in front (or not), with the open back on the back of the head. If the lady had a bun or chignon hairstyle, the opening would help to keep the hat from flattening out her hair do.

Something like this, just to give an idea. I could not yet find a better photo of the style.

 

Reminds me of Audrey Hepburn's turban-style hat in Sabrina. That's how I'd suggest it be worn!

 

That's it!
