Blonde bombshells: Sienna Miller and Cate Blanchett party in New York

Aside from the news that she's pregnant with her first child, Sienna Miller has stepped out of the spotlight over recent months. So we were pleased to see the mum-to-be make her return to the red carpet last night at The Ever Changing Face of Beauty party in New York.

Miller was blooming in a floor-length gown by Boss Black paired with a statement necklace and cuff from Pamela Love. However, there were a few other blonde bombshells in attendance to give Sienna a run for her money on the style front.

Cate Blanchett also got the memo about wearing black. She looked gorgeous in a Juan Carlos Obando design teamed with cherry red lips and a side swept updo while Evan Rachel Wood opted for a chic, strapless peplum dress, but in a dull, charcoal shade.

Olivia Palermo teamed her skinny trousers with a sheer, ruffled top (we're not sure about those ruffled cuffs) and Coco Rocha looked pretty in polka dots. Thank goodness for model Liya Kebede, who shunned the black trend by turning up in the exact opposite of Sienna's sleek dress. Ruffles and a colourful print? Kebede proved it can be done.
