Meghan Markle wows in Stella McCartney for second wedding dress: Pics!

Why have one wedding dress when you can have two?! After Meghan Markle stunned in a custom Givenchy gown featuring a 15-foot veil, the bride switched into a gorgeous Stella McCartney dress for their evening reception at Frogmore House.

The pure white gown from the British fashion house features a high neckline and is made of silk crepe, while her Aquazurra shoes are silky satin with the soles painted in baby blue (her something blue!).

The former actress looked like she had redone her hair and makeup -- rocking a similar bun from this morning with a few strands framing her face, while her natural makeup accentuated her natural beauty.

The newlyweds, who are now the Duke and Duchess of Sussex, were seen arriving at Frogmore House, a 17th-century venue in the grounds of Windsor Castle, in an electric Jaguar.

Only 200 guests are invited to the intimate evening reception where Meghan is set to make her history-making speech later in the night. Late night TV host James Corden will reportedly play host and entertainer for the reception.

Earlier in the day, Meghan and Harry tied the knot at St. George's Chapel in front of a star-studded crowd which included George and Amal Clooney, Serena Williams and the rest of the "Suits" cast. From the veil to the bouquet, the royal wedding featured special details chosen by the couple.
