Post American Civil War Bonnet

From the seller:

DESCRIPTION
Truly wonderful antique Victorian Civil War 1860’s era woven bonnet/hat with velvet & ribbon. The base of the hat is a woven straw type material and it is embellished with periwinkle blue ruching on the top of the hat and adorned with blue velvet daisies and ivory velvet leavesand gross grain ribbon bow. It is lined in silk (some age to it) see pictures for details, and ties just under the chin with a blue and gray gross grain ribbon. The ribbon is still in place, but is deteriorating. The original design is still in place and can authentically be repaired. Also the hat has a thin wire to hold its’ shape, that need a couple of stitches to hold it in place.

From Me:

I'm very curious if this bonnet was for half mourning. The flowers look black to me (maybe a faded black, but black) and I wouldn't be surprised if some of the "ivory" was originally white. The bonnet itself fits the later styles that were worn in the early Bustle period.
