Rubie'sForum Novelties Men's Costume Spanish Hat

Can anyone tell me how big the rim is? As in how many inches is the whole thing? The description says 1x1x1, I don't think that's right.

My head is is oval shaped. How flexible is the hat?

How flexible is the brim? I'd like to fold one side up and pin it to make a cavalier hat. Would I be able to do that with this hat?

My head is an XL will this fit?
