This is a fabulous celebration hat. I have taken the traditional style of a boater and elevated it! 
The hat is made from sinamay and petersham and lined with a vintage scarf. It is a total one off.
It sits to the side of your head and is held in place with an elastic that sits under your hair at the back - as a seasoned hat wearer I feel this is the most secure and comfortable way to wear a hat of this scale.
