Each dazzling in different shades of blue, Hollywood's leading ladies descended on New York on Thursday night for the Blue Book Ball thrown by Tiffany & Co. Gwyneth Paltrow lead the glamour brigade in a teal satin Ralph Lauren gown with cutout shoulders. She paired the showstopping creation with Jimmy Choo shoes, a sparkly Tiffany brooch and poker-straight locks. Chris Martin's wife was asked which piece of jewellery means the most to her during the evening. "Probably my engagement ring," she replied.
Gwyneth was joined by Jessica Biel, who was as stunning as ever in a daring Elie Saab sheer halter-neck gown that featured strategically-placed blue and purple flowers. Side-swept curls and a jewel-encrusted bracelet completed the Old Hollywood look. Kate Hudson, meanwhile, had flashbulbs blazing as she stepped out in a strapless duck-egg blue Reem Acra gown with a thigh-high split. The 33-year-old actress stunned in the designer number, teaming it with sparkling Tiffany earrings and a nude clutch. Michelle Williams also attended the ball, which took place inside a 31-foot high Tiffany box specially erected for the occasion. The former Dawson's Creek star wowed in a navy blue, high-necked dress that accentuated her small waist. Her wrists and ears were adorned with Tiffany jewels. Michelle was also asked to reveal her most meaningful piece of jewellery. "That's tough. Something my kid made forme," she said, referring to her daughter Matilda.
Other stars opted to eschew the colour code and opt for more striking hues, with Sarah Jessica Parker wearing a floor-length gold gown and a black tuxedo jackets. The Sex and the City star spoke about her engagement ring, which was by Tiffany, and cited it as the piece of jewellery that is most precious to her. "I've told him countless times," she said, referring to her husband Matthew Broderick. Sarah also revealed that she never buys jewellery, as she is lucky enough to be able to borrow. "I never bought jewellery," she said. "It never occurs to me that's a possibility. We've been so privileged to be able to borrow things. "It's such an enormous privilege," she added.
