Three months after giving birth to Prince George back in July, Kate Middleton takes a morning off from baby duties, and hits the volleyball court in her tight skinny jeans and sky-high wedges.

The Duchess of Cambridge attended a SportsAid Athlete Workshop at the Copper Box in London's Queen Elizabeth Olympic Park, where she showed off her impressive volleyball skills and amazing post-baby body, as well as her classy dress-down.

In her Ralph Lauren Breton-style striped top, a navy-blue military blazer by Smythe, cropped J Brand jeggings, Stuart Weitzman for Russell and Bromley "corkswoon" wedges, and Kiki McDonough earrings, Middleton looked super-slim and absolutely stunning, not to forget her surprisingly flat stomach and in-shape body. The casual outfit reminded everyone of the outfit she wore during a visit to the Olympic Village in August 2012.

Established in 1976, SportsAid is a charity aimed at helping and organizing young British athletes. It has offered support and financial assistance to many talented athletes, including two-thirds of the British team at the London 2012 Olympic and Paralympic Games. Kate Middleton became a patron of SportsAird earlier this year after being inspired by the success of Team G.B. and ParalympicsGB at the 2012 London Games, where the royal couple regularly cheered on the British athletes.

Middleton talked to the aspiring athletes and watched them in action, playing various games such as badminton, volleyball, fencing and wheelchair basketball. She met a few volleyball players and agreed to join them for bit saying, "I'll try my best." The Duchess also was asked to take part in a fencing match but she declined, "I'd like to give it a go but I've brought the wrong shoes."

Kate Middleton then joined several athletes and their parents for some educational workshops and about media, nutrition, and general guidance from Olympians and Paralympians including Katherine Grainger and Ade Adepitan.

Since Prince George's birth, Middleton appeared in public twice before with Prince William, kicking off a marathon in Anglesey and attending the Tusk Trust Awards. This was the first time she has stepped out on her own, which signifies that she is starting to be more active in royal duties.
