Vintage 1960s Christian Dior Ivory Felt Feather and Gold dipped hat

Beautiful, vintage 1960s Christian Dior felt, ladies hat. Gold webbing with hand selected white feathers that have been then dipped in gold and placed around the brim. This is in vintage condition. The feathers have slightly come away from the brim (attached to the webbing). They can be reattached but I’m unsure how to do so, so I haven’t. This was my grandma’s and it should go to someone that can revive it and bring it back to its former glory.
