Meghan Markle stuns in gorgeous Givenchy wedding gown: Pics!

There she is! After months of anticipation, Meghan Markle made her debut as Prince Harry's bride. To say she looked stunning would be an understatement.

The Duchess of Sussex looked absolutely breathtaking in a pure white gown from Givenchy. The simple, yet sophisticated and elegant gown, features a "bateau neckline" that softly frames her shoulders and emphasizes her teeny waist. The structured design of the gown was accomplished with only six "meticulously placed" seams. As for the material of the dress, Meghan opted for a double bonded silk cady in a pure white hue, which brings a "fresh modernity" to the dress.

According to a press release from the Palace, Meghan chose to work with Keller because of her "timeless and elegant aesthetic, impeccable tailoring, and relaxed demeanour."

For her big day, Meghan styled her brunette tresses in a delicate updo and dramatic veil with a tiara. The bride chose to wear Queen Mary's Diamond Bandeau Tiara, which is on loan from the queen. The tiara's diamond bandeau was made in 1932, while the brooch on the center dates back to 1893. She completed the look with earrings and a bracelet from Cartier and a pair of custom Givenchy stilettos.

As for her makeup, she let her natural beauty shine through with a dramatic smokey eye, a pale pink lip and a hint of blush that accentuated her high cheekbones.

The bride's decision to wear Givenchy came as a total surprise for many because many thought that Meghan would opt for a British designer. However, the new artistic director of the French fashion house, Clare Waight Keller, is British herself.

Ralph & Russo was tipped to be the designer of the gown after reports broke that Meghan purchased a £100,000 dress from the fashion house. Prince Harry was reportedly even seen leaving the atelier weeks before the wedding.

The 36-year-old former actress left luxury hotel Cliveden House on Saturday morning with mom Doria by her side. Prince Harry spent the night at a different hotel -- Coworth Park -- with best man and older brother Prince William.

After she left the hotel, Meghan began her journey to St. George's Chapel inside the grounds of Windsor Castle, where she will marry Harry at around 12 p.m. London time. Following the ceremony, the guests will make their way over to St. Georges Hall for a reception. Later in the day, Meghan and Harry will host an evening reception for VIP guests at Frogmore House.
