Talk to me about summer hats!

[eternityleave]

So my much loved floppy cotton summer hat (by La Senza, which tells you how old it is!) finally gave up at the end of last summer and with the hot weather hopefully approaching I'm now in the market for a new summer hat.

So what's the fashion at the moment? I see a lot of straw hats (would rather have something more sturdy) and there's a fair bit of felt/wool out there. I want a proper hat with enough coverage for my head since I burn a lot.

What are the rest of you buying/admiring in the world of hats?
