Clad in an all-sequined dress, Catherine, the Duchess of Cambridge, made a dazzling first official appearance since the birth of Prince George as she attended the Tusk Conservation Awards on 12 September.

Kate Middleton attended a dinner gala for the Tusk foundation at The Royal Society. The 31-year-old Duchess was accompanied by Prince William, the Duke of Cambridge, who is the royal patron of the foundation that funds environmental conservation works across Africa.

Kate wore a glittering floor-length gown by Jenny Packham to the red carpet event. The bespoke gray-coloured dress decorated with silver sequins flattered a slim-figured post-baby Kate, who is in the tenth week of motherhood. She completed her sparkling ensemble with a pair of matching silver stilettos by Jimmy Choo and diamond jewellery.

The Duchess of Cambridge looked stunningly attractive in the shimmering number as her trademark, glossy blow-dried hairdo upped her beauty quotient.

Kate Middleton's Pregnancy Weight

Kate Middleton has made a few unofficial appearances as well since the birth of Prince George, and, though still chubby-cheeked, she has stunned observers with her slim post-baby body at every instance. Kate was first spotted in Anglesey without her baby bump, just five weeks after the royal baby was born.

Prior to Anglesey, the first family photograph of William, Kate and George showed off the duchess in remarkably slim post-pregnancy shape.

More recently, during an ultra marathon event in north Wales, Kate's first public engagement since the birth of the royal baby, she appeared to have shed all her pregnancy weight. For the event, the Duchess donned a fitted green Ralph Lauren jacket over a Zara blouse and a pair of skinny black jeans.
