Chinese Wedding Cap

This Chinese hat or cap is more like fascinator than an actual hat.

 The cap come up in images under Qing and Han Dynasty, I can only assume it was worn across both periods.

Used by nobles, emperors and as a modern wedding headpiece.

This hat is held in place by a tie, although it's more likely to have been pinned through and over a bun of hair, but I don't have anywhere near enough hair for that.

Also seen listed as a Chinese landlords hat

Dreadlock hat

This is a novelty dreadlock hat.

In the colourful style of the Caribbean, this hat comes complete with dreadlocks attached to the rim of the hat. 

It also includes a small zip pocket to keep something lightweight in, maybe tobacco or paper money.

You will also find them under Rastafarian hats, reggae hats. 

As sold to tourists.

Floppy Felt Hat

This is a felt hat with an oversized brim.

Not really much more I can say about it.

I folded the front of the brim up to give the brim some support via the crease.

Uses 

Useful to protect your shoulders from the sun.

 You could fold the brim upfront and back so it meets in the middle forming a nice bicorne.

or fold in 3 making a an oversize tricorne.
