There are so many options...linen, straw, white, black, colors, etc.
I already have a white linen hat from H&M last year but I wanted to update the hat collection and found this awesome black and white patterned fedora. It's from Express and would be the perfect compliment to top off a black maxi dress. Wear your hair in a cool side braid and top with the fedora, ultra chic and on trend.
