Kate Middleton dazzles in green lace gown

She sure knows how to turn heads with her impeccable fashion sense and the Duchess of Cambridge did it again last night at the National Portrait Gallery.

The stunning 35-year-old mother-of-two arrived at the event wearing a floor-length green lace gown by Temperley London.

Kate smiled from ear-to-ear as she dazzled in the intricate lace gown, which was similar to the black Temperley dress she wore to the War Horse premiere in 2012.

The dress features an upper bodice, cinched in at the waist with a dark green belt.

In a daring move for Kate, the gown scoops down the back and the sleeves are lined with green lace.

The Duchess accessorized her outfit with a $300 gold clutch bag by Wilbur and Gussie and a pair of gold, strappy Jimmy Choo shoes.

She wore a pair of shimmering 18-carat yellow gold earrings by Kiki McDonough, which were slightly obscured by her perfectly blow-dried hair.

Kate is an avid art fan and she famously studied art history when she attended St Andrews.

The Duchess is the patron of the National Portrait Gallery and was shown around the building, showing keen interest in artwork on display.

According to the Daily Mail, Kate was introduced to the parents of a child who attends Thomas’s School in Battersea, where George is set to enroll in September.

'We were chatting about Thomas', the school George will be going to,' Richard Found said.

He also revealed that they told Kate she and William had picked a “great school” for George and she replied saying they might bump into each other “at the school gates”.
