Kate Middleton stepped out to do some grocery shopping for her new family, unveiling her svelte frame one month after she gave birth to a baby boy.

Us Weekly reports that the Duchess of Cambridge was spotted earlier this week in Anglesey, Wales, where her husband, Prince William is stationed as a helicopter pilot for the Royal Air Force. She was seen doing some grocery shopping at a local Waitrose supermarket, dressed in a white and black striped shirt and black skinny jeans. Reportedly, she seemed to have lost all the weight she gained during the pregnancy. Her son was born on July 22nd.

Celebuzz reports that she wore the same Sebago flats on an appearance in Canada in 2011. Her top has been identified as Ralph Lauren and her sunglasses as Givenchy. Middleton will make her first official appearance post-baby at an engagement for the Tusk Trust. She will join her husband at a gala for the organization because he is one of its patrons. The Duke of Cambridge has videotaped a special regarding the organization's work in Africa and his life as a new father for CNN. It will air on September 15th.

Apparently, Middleton has lost the weight naturally. "She's hardly done anything to lose the weight...She looks incredible. Kate's still breastfeeding and the small weight she gained while pregnant has just melted off. She's not dieting. After giving birth, she did continue with her yoga."
