Help me replace a stolen hat with sentimental value

Hoping to find a way to replace my partner''s favourite cap that was taken by an attempted pickpocket.

It was clipped onto the shoulder strap of their bag. Very lucky they didn't manage to open the zip and get any cash but my partner was devastated to lose their favourite headwear.

I found an old listing for a similar one online at the Iconic but it's no longer sold there.

The brand is Spencer project. I think it was purchased early 2010s. It's a darkish green and is ladies/unisex.
