Michelle Williams wows at Tiffany ball in midnight blue gown
The actress joined a whole host of Hollywood's A-list at the Rockefeller Center in New York City to celebrate the iconic brand's unveiling of its latest Blue Book collection.
Guests at the swanky bash assembled inside a 31-foot-high Tiffany box erected for the occasion.
Michelle stood out in her boxy shaped high-necked frock that accentuated her small waist through the severe structuring of the dress at the midriff. She also wore Tiffany gems on her wrists and ears, which drew attention to her newly cropped sweeping hairstyle and petite features.
Michelle was asked which piece of jewellery means the most to her during the evening.
"That's tough. Something my kid made for me," she told USA Today, referring to her daughter Matilda.
Other glamorous stars at the Blue Book Ball included Gwyneth Paltrow, Kate Hudson and Jessica Biel.
The leading ladies all honoured the theme by joining Michelle in wearing blue gowns and diamonds for the occasion.
Gwyneth looked beautiful in a Ralph Lauren silky blue gown which had long sleeves but bared her shoulders.
The blonde actress wore minimal make-up and wore her platinum blonde hair in a loose straight style.
Gwyneth also revealed her most meaningful piece of jewellery.
"Probably my engagement ring," she replied.
Sarah Jessica Parker wore a floor length gold gown to the party, with a tuxedo jacket and Tiffany blue jewels.
The Sex and the City star gushed about her engagement ring, which was by Tiffany, and said this item means the most to her.
"I've told him countless times," she said about her husband Matthew Broderick's choice of ring.
Sarah revealed she never buys herself diamonds, as she is lucky enough to be leant them for free. The mother of twin daughters also said her girls will inherit her jewels when they get older, after showing early signs of appreciation for her gems already.
"I never bought jewellery. It never occurs to me that's a possibility," she admitted to USA Today. "We've been so privileged to be able to borrow things. It's such an enormous privilege. [My toddlers love my jewellery] It's not off-limits. They're welcome to it. They really love it."
