I have a Dorfman-Pacific bowler that has a good fit and pleasing shape.  It just happens to be bright purple to match the zoot suit I wore when I was DeeJaying back in the neo-Swing era.  I found the hat at a little shop in downtown Seattle back in the late nineties.  I don't wear it all that often, but it has held up well.

I've never been a big fan of the bowler.  I much prefer the Homburg for a dressy hat.  Good luck with your search!

I have two - both black:  A vintage Glyn & Co. (London), that is too snug and whose ribbon edging is in dire need of replacement - I don;t wear this one, really, and a newish one by Park Royal, which looks great, but is not as sturdy.  However, I do wear that one in the fall/winter.  I am wearing it in my avatar....
