What could be more iconic of Jane Austen's era than a lovely wide brimmed straw sun bonnet?! This brand new style is based on the period bonnet seen in the photograph (below) from the Kyoto Institute (dated 1790-1815) It also reminded me of this portrait of Mme. Seriziat, 1795 and fashion plate from The Gallery of Fashion, 1794-1798. The trimming possibilities are endless on this fantastic bonnet.
