All about Meghan Markle's wedding dress

Meghan Markle was a vision in white as she walked down the aisle to Prince Harry.

As the bride, now known as the Duchess of Sussex, walked into St. George's Chapel Saturday, in front of more than 600 guests and millions watching around the world, she wore Queen Mary's diamond bandeau tiara, lent to Markle by Queen Elizabeth, complete with a flower-outlined veil that measured at five meters long. The actual tiara, which features a diamond bandeau, was crafted in 1932.

And one more detail about Markke's veil's flower details. They represented the "53 countries of the Commonwealth," according to a press release from Kensington Palace.

Her signature messy bun was polished into a low chignon, and the duchess had short nude-polished nails as she waved to crowds while entering the chapel.

The wedding gown, made out of triple silk organza, featured an open bateau neckline with three-quarter-length sleeves.

It was designed by British designer Clare Waight Keller, 47, who became the first female artistic director to head the house of Givenchy.

"After meeting Ms. Waight Keller in early 2018, Ms. Markle chose to work with her for her timeless and elegant aesthetic, impeccable tailoring, and relaxed demeanour," a press release from Kensington Palace read. "Ms. Markle also wanted to highlight the success of a leading British talent who has now served as the creative head of three globally influential fashion houses -- Pringle of Scotland, Chloé, and now Givenchy."

Markle's shoes were also Givenchy.

The bride's mother Doria Ragland, who walked in ahead of the bride, wrote mint green, with a silver hat that complemented the look.

Queen Elizabeth also wore the color green, opting instead for a lime green suit with matching hat that featured a royal purple ascent.

Previously, it was rumored that British design duo Ralph & Russo would have the honors of designing Markle's wedding dress. She selected the Australian-born designers, Tamara Ralph and Michael Russo, to wear for her engagement photos to Prince Harry last December.

That floor-length Couture gown was semi-sheer with hints of gold leaves, creating a winsome look. The top is paired with a feathered semi-sheer skit.

Other designs rumored to be in the running to design Markle's dress have included Christopher Bailey, the man behind the iconic British brand Burberry, British designer Stella McCartney, Canadian designer Erdem Moralioglu, and Roland Mouret, a close friend of the former actress.
