This is not my hat.
Google image of Union Zouave.
The Zouave were French. Granted, they did fight in the American Civil war. But the traditional Union uniforms were entirely blue. I do think our uniforms reflect the Ohio heritage.
The only complaint I have really about our uniforms, is I think the flag swoops around the star in the wrong direction. How they thought it should go from right to left is beyond me.
