Kate glows in a baby blue Jenny Packham gown

This evening, the Duchess of Cambridge stepped out for her second engagement of the day, attending the 50th Annual Wildlife Photography Awards at the Natural History Museum in London, of which she is Royal Patron.

Only hours after attending a ceremonial welcome for the President of Singapore, the Duchess of Cambridge made a wardrobe change for this evening's black-tie event wearing a bespoke pale jade Jenny Packham creation. 

The maxi wrap dress was the perfect choice for the Duchess who is about 3 months pregnant with her second child.  The gown features a three-quarter sleeve with a wrap front surplice neckline and a lightweight envelope skirt with a pee-a-boo short hem skirt underneath.

The silhouette of Kate's bespoke gown appears to be modeled on this Jenny Packham A/W 2014 Cruise collection piece.

Kate accessorized the dress with a new clutch bag from Alexander McQueen. Like all her other McQueen bags, Kate had this one modified with the removal of the signature skull clasp.  The small curved molded clutch is rendered in a gradient nude pink python leather with gold metal frame.

Kate paired the clutch with her blush pink LK Bennett Agata suede sandals, first seen at the 2011 annual ARK  dinner.

This evening, the Duchess donned a new sparkling diamond necklace and matching earrings.

The pieces are from the Monica Vinader 'Riva' collection (thanks to My Small Obsession for the ID). Kate wore the 'Riva' Diamond Cluster Bib necklace which is a Harrods exclusive according to Monica Vinader's Instagram page.
