I just sold an authentic 20s Panama hat that was exactly the same shape and weave as this amazing Frank Olive designed early 60's hat.

Its in amazing condition and even the tag looks as if it has never seen wear.

Just a stunning hat and timeless. Frank Olive was a leading millenary designer for Saks 5th Ave before moving on to top designer Emmes Boutique.

I included a photo of the models crown being taped so you can see it fits this size fine with the full hair style and some room in hat. I do not have a proper hat measurement tool, they are very very expensive so I use a round tape but this is not 100 percent accurate its hard to keep tape firm all the way around especially with softer hats. So this is an apx but the crown on model is an accurate.

Model crown with hear is 21"

The apx measurement of inner crown of hat show 20. 5" I would say 21 is more accurate and probably 21. 5" to 22" is possible.

This item is sold from an excellent, highly rated vintage boutique in Beautiful Eastern Wa.
