HAT SEARCH

The last time V and I traveled to New York Rachel Bilson was ahead of us in customs wearing a hat like this. During the trip we looked for one (which we now call the 'Bilson Hat') but kept coming up empty handed. In February we're heading down to Mexico where I'm hoping to shoot the Spring lookbook and would LOVE to find a hat like this for the shoot. Do any of you have any suggestions as to where I can grab one before we leave?
