Kate Middleton once again recycled a dress that she wore three years back by British designer Mathew Williamson. She headed for a sole engagement at the Place2be Headteacher conference in London Wednesday. The royal made a rare public speech focused on the issue of child mental health.  

The 33-year-old looked chic in the gray shift dress by Mathew Williamson. It is from the designer’s pre-fall 2012 collection. The sleek outfit featured three-quarter length sleeves, high neck with exquisite teal and gold beaded embroidery around the neckline and the sleeves.

The form-fitting knee-length dress showed off Middleton’s slim figure and waist, while it had a slight peplum detail on the waistline. The Duchess of Cambridge first sported the same dress back in April, 2012. She had worn the gray confection for the U.K. premiere of  Disneynature’s “African Cats.” The dress is already sold out.

The mother-of-two paired her wool-crepe dress with a clutch bag and matching rounded-toe high heels. Kate added bling to her look as she accessorized with a pair of her Lauren Yellow Gold Pave Diamond Leaf Earrings by Kiki McDonough and her wedding ring. She wore her favorite silver Cartier watch.

The earrings are beautiful and elegant and made of 18 carat yellow gold and pave diamond leaf motif drop earrings. They are inspired by the British ballerina Lauren Cuthbertson. Kate often sports designs from the British brand, who also designed jewelry for Prince William’s late mother, Princess Diana.

Her long brunette tresses were left loose over her shoulders in a glossy blowout. Her flawless make-up consisted of kohl lined eyes, black eyeliner and pink blush and lipstick.

Middleton opened up about her happy and healthy childhood, saying that she was “lucky” to grow up with such supportive parents. In a three-minute speech she confidently addressed the head teachers. This was one of her rare public speeches since she married William. Kate is reportedly been receiving public speaking and media training recently.

She is now going to focus more on public speaking during her various engagements to overcome her fear to speak in front of people. The 33- year-old royal spoke to students from The Crescent Primary School. She later headed into the conference where head teachers from England, Scotland and Wales had gathered to discuss the role that schools can play in promoting good mental health in children.
