Fascinator

This lady certainly caught my eye! And in the process, I learned something new: a 'fascinator' is a form of formal headwear, worn as an alternative to the hat, usually a large decorative design attached to the hair by a band or clip. If it incorporates a base to resemble a miniature hat, it's then called a 'hatinator.'  Must try this someday as regular hats don't seem to suit me ;)
