Assam White and Black Saucer Hat

"A classic Lock shape reimagined for the new season. The polka dot twirling quills add a little frivolity to the hat" Awon Golding, Head Millinery Designer. 

A wearable monochrome palette that goes with so many ensembles. The Assam is an ivory white sinamay saucer hat with white silk camellia detailing and spiralling black sinamay bows complemented by black and white polka dot ostrich quills. This hat is perfect for Royal Ascot and also makes for a great wedding guest hat.
