I don't actually know a whole lot about this hat, so I'm sorry to say that most of this information will be guesstimates...

It is a brown wool velour cloche / peach basket style vintage ladies hat, believed to be from the 1950-1960s. 

It has no marks to indicate where it was made or by whom, so your guess is as good as mine.

What I do know is that this intriguing piece measures approximately 6.25" H and has an inner circumference (at the rim) of approx. 21.5". It is slightly shorter in the back and front and the brown ribbon detail splits the hat into three "tiers", if you will.

The only flaws that I have found are:
1) It smells a little musty;
2) The ends of the ribbons are discolored slightly and were cut poorly, so I would trim them;
3) It needs a lint brush.
