Caron Cakes (about 1/3 of a cake) in Pistachio
G Hook (Furls)
http://www.ravelry.com/patterns/library/elegant-hat-200. This is a free pattern from Crochet Kim.
I added rows after rows 25 and 32. If I make this again I would add a few more rows to the brim. It fits my massive noggin but if I make it for anyone else, I will go down a hook size to my (recently overworked) Furls F Hook.
