Garbo hat. The High Street calls them Floppy hats. They're in a lot of places here. I saw a white one just like that in Jigsaw,it was around £70. Other places do them way cheaper. Like H&M were doing them in black and brown for £10, Topshop for £20 in black and brown, and now H&M are doing them in straw for £5. I think Tesco did some too!
