Decorator crabs make fascinators seem lame in comparison to the extravagance of their accessorising.
There are hundreds of species of crabs which decorate themselves in this way and fashion really has nothing to do with it. It’s all about survival.
By attaching algae or sponges of their immediate environment they can go about their business unnoticed.
If they move into new territory it’s a simple matter of discarding the old and accessorising with their new home.
