Daisy's (Carey Mulligan) pièce de résistance? The Savoy, Tiffany's diamond and pearl headpiece with detachable brooch.
Zoe Saldana demonstrated a modest way to wear a crown: tucked into a retro-roll.
Not all of Daisy's hair flair involves of bling, she also models how to look chic in a silk scarf. The earrings do add a bit of sparkle, though!
For a casual take on the scarf effect, Eva Mendes updated her simple pony by adding a leopard-print version.
Make the scarf look black-tie ready by tying a delicate lace headband over an undone updo like Olivia Wilde.
Diamonds may be a girl's best friend, but pearls take a close second. In The Great Gatsby, Daisy's wrist and neck are dripping pretty pearls by Tiffany and Co.
Proving that the classic bead can also work as hair flair, Emmy Rossum displayed a pearl-adorned headpiece.
