Last night, the Black Swan star (and February cover girl!) wore a halter-style Vena Cava sheath to the premiere of her latest film, No Strings Attached, and she recently wore a Vionnet dress with studded collar and cuffs to the Palm Springs International Film Festival Gala and a Jason Wu silk chiffon tiered dress at the People’s Choice Awards. As Portman’s pregnancy progresses—and she gears up to walk the Golden Globes red carpet this Sunday—she has plenty of well-dressed celebrity moms to take style cues from.
