I agree with the first review about Target hats. I bought a white, wide brimmed one in 2009 and just wore it again this week. For $15 it was a great hat then and is now and I expect it to last. The style is timeless, pretty much.
I bought the same wide-brimmed hat from H&M in black and maroon and am in love with them! They go with about any oufit and they aren't too wide to the point where you have to crane your neck everytime you want to look a certain way!
