- the best-dressed list
Michelle Obama, 48
The election may have hung in the balance, but the First Lady always led in the style stakes. From the J Mendel number she donned at the Olympics to the Jason Wu ballgown she wore to a state dinner, Mrs Obama's graceful athleticism lends every look a presidential air.
Jessica Chastain, 35
With a Broadway debut and an Oscar nomination, 2012 has seen Chastain's star go stratospheric. Glittering in Gucci or scene-stealing in Stella McCartney, her natural American beauty sets her apart.
She's the Veronica Lake of the 21st century. Whether wearing striking gowns or sensational cocktail mini dresses, the British model has proved she's an old-school Hollywood siren.creditsPhotographs: Rex Features; Getty Images
