This hat is great!  It fits chidren as well.  I bought it for my 4 year old son for his  Mickey Mouse costume.  It really made the costume look so much better.  Many people thought I made his costume since it looked so much better than the ones with standard ears.  It kept his head warm on the cold Halloween day, too.  The only negative is that when I tied the strings around his chin, the pom poms hung in the way of his cotume.  I ended up tying them so that the pom poms were right under his chin, so they didn't block his costume.  I assume that most adults would not bother to tie the strings/pom poms when wearing it, though.
