Stunning! Just hours after Meghan Markle and Prince Harry said "I do" in a lavish wedding ceremony fit for royalty, the newly crowned Duchess of Cornwall wowed fans by stepping out to her wedding reception in a second dress — a sexy, backless Stella McCartney number that showed off her toned arms.

Meghan accessorized her silk "lily white" halter top gown with custum satin Aquazurra shoes that featured a baby blue sole, according to People. To complete her second look, she changed her hair into a sleek updo by hairstylist George Northwood.

Meghan's new hubby, Prince Harry looked dapper as ever in a classic black and white tuxedo and he held onto his new wife's hand as they walked to a silver blue Jaguar E-Type Concept Zero that was waiting for them outside. Harry drove off to the reception at Frogmore House on the grounds of Windsor Castle, which was hosted by his father Prince Charles — who had a very special role in the wedding ceremony as he walked Meghan down the aisle and handed her off to his son.

But Meghan's shoes and the couple's car wasn't the only thing that was blue! Meghan paid tribute to her husband's late mother Princess Diana by wearing Diana's gorgeous, emerald cut aquamarine ring on her right hand, according to People. Diana wore the ring to an auction at Christie's in 1997, and more two decades later, the stunning ring sparkled as Meghan waved to the cameras.

The wedding reception is the second party that Meghan and Harry will be attending on their wedding day. After they exchanged their vows during their wedding ceremony, the couple waved to crowds that gathered in the streets of Windsor in a procession on their way to a wedding breakfast hosted by Harry's grandmother, Queen Elizabeth, according to E! News. The second reception is expected to be more intimate with only about 200 guests — which is a significantly smaller guest list than their wedding ceremony.
