Last night, the Burberry boutique in Beverly Hills hosted a small cocktail gathering to showcase their spring collection and celebrate The Bolter, author Frances Osborne’s biography of her great-grandmother, scandalous Jazz Age socialite Idina Sackville.

The most eye catching piece of the evening wasn’t Burberry’s short, straight-off-the-runway silver sequined trench coat (the only one currently in North America, apparently). But instead a tid-bit inside The Bolter’s book jacket that said Sackville was muse to famed couturier Edward Molyneux and helped put the wraparound dress that became synonymous with Art Deco fashion on the map.

HuffPo has a photo gallery of Sackville’s style complete with captions by Osborne.

I wouldn’t mind seeing that silver coat hanging in my closet, but seeing Molyneux’ 1938 black crepe v-neck there instead (right) would leave me speechless.
