Meghan Markle's wedding dress

Meghan Markle looked absolutely divine on her wedding day. 

Meghan picked a sleek sculpted dress by Givenchy creative head Clare Waight Keller for her wedding to Prince Harry on Saturday, worn with a five-meter long veil and a diamond tiara lent by Queen Elizabeth.

Details of the dress were kept under tight wraps and not even Prince Harry saw her before the wedding. 

Meghan walked the aisle by herself first, before being walked to the altar by Prince Charles.

The long-sleeved dress with a boat neck had been eagerly anticipated by royal fans around the world, with speculation over which designer would be chosen.

"Waight Keller, previously at Pringle of Scotland and Chloe, became the first female artistic director at famed French brand Givenchy last year.

The 47-year-old met Meghan earlier this year and the two worked together on the design, which "epitomizes a timeless minimal elegance", Kensington Palace said.

"The focus of the dress is the graphic open bateau neckline that gracefully frames the shoulders and emphasizes the slender sculpted waist," the palace said in a statement.

"The lines of the dress extend towards the back where the train flows in soft round folds cushioned by an underskirt in triple silk organza. The slim three-quarter sleeves add a note of refined modernity."

Meghan's long veil, made of silk tulle, was decorated with hand-embroidered flowers in silk threads and organza, the palace said, and paid tribute to the 53 countries of the Commonwealth.

"Ms. Waight Keller designed a veil representing the distinctive flora of each Commonwealth country united in one spectacular floral composition," the palace said.

Prince Harry last month was appointed a Commonwealth youth ambassador. — with reporting from Reuters / AT, GMA News
