The hat is slightly smaller than my head.  I bought for my niece but ended up giving her mine instead.  I am working on it, though.  It is really stiff, though it holds its shape and I found that if I pulled the decoration loose the band would stretch.  I am going to reshape and work with my hands until I get it into usable condition.  They made poor work of attaching the beaded band and it is just strings in the back.  Would I buy it again? Probably not, though my hat that I gave away was a bargain years ago and not easy to find. My old hat cost around twice as much.  P.S. I do not have a big head, really.
