I highly recommend these Scala large-brim hats The black one makes you look like you're going to breakfast at Tiffany's and the rest of the colours are great too. The best part is they are foldable and when you unfold them they still hold a great shape. I've had mine for at least two years now and they still look great. Just don't put them in the dryer because that's how my red one became a smaller brimmed hat.

I bought this one a few years ago. I got it in black and it looks great... like I'm in the cast of American Horror Story: Coven ��
