I read the reviews prior to purchasing this Fedora.  Some said it ran really small and I was concerned because the only size available was s/m.  I went ahead and ordered it, and boy am I glad I did.  I have very thick hair, but it's actually a little big, but no worries, it works just fine.  I'm very pleased with my purchase and it looks great with just about anything I wear.  I'm glad I took a chance.
