This is some mad hattery!
Two of Kate Middleton's hats worn during her pre-Duchess of Cambridge days will be up for grabs later this month at the Passion for Fashion auction, hosted by Kerry Taylor Auctions.
Both the black feathered Aurora hat worn at Prince William's Order of the Garter in 2008, and the feathered Philip Somerville head topper worn in October 2010 at Harry Meade's wedding were custom-made for Kate and are expected to fetch at least $1500 each.
The highest bidders will also get receipts and copies of the milliners' diary entries from the Duchess' appointments.
For those in the Bermondsey area, the auction will take place on June 26 at the Kerry Taylor auction room.
