Meghan Markle has chosen to wear a gown designed by Clare Waight Keller for Givenchy for her wedding to Prince Harry.
The newly appointed Duchess of Sussex arrived at St George's Chapel in the Givenchy gown and Queen Mary’s diamond bandeau tiara, which was held in place by the veil.
The tiara was lent to Meghan by the Queen and was made in 1932, while her beautiful gown features a bateau neckline, extraordinary long trail and three-quarter sleeves.
Meghan descended down the aisle, meeting a nervous Prince Harry at the altar. He held her hand and told her, "You look beautiful."
A statement from Kensington Palace gave more information on Meghan's beautiful gown, reading, "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.
"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.
"True to the heritage of the house, the pure lines of the dress are achieved using six meticulously placed seams. The focus of the dress is the graphic open bateau neckline that gracefully frames the shoulders and emphasises the slender sculpted waist.
"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."
Both Prince William and Prince Harry wore the frockcoat uniform of the Blues and Royals, which the Queen granted Harry permission to wear to marry.
They were both tailored by Dege & Skinner on Savile Row.
Around 2000 guests also attended the nuptials, including celebrities Idris Elba, Oprah Winfrey, The Beckhams and Serena Williams.
Meanwhile Meghan's beloved mother Doria Ragland looked emotional as she watched her daughter wed into the Royal Family, becoming the Duchess of Sussex.

Meghan Markle's bridesmaids - Closer (slider)
1 of 11Serena Williams
Someone with an outside shot at being Meghan's bridesmaid is tennis ace Serena Williams. Meghan and the Wimbledon-champion have been friends since 2014 when they met at a charity football game. Despite their reported closeness, Meghan didn't attend Serena's own nuptials earlier this year, so it might be that she doesn't have a role at the royal wedding.
2 of 11Janina Gavankar
Fellow actress Janina Gavankar has known Meghan for 15 years, with the Suits star recently gushing about their friendship in an Instagram post that read: 'Couldn't be prouder of how far we've come, and couldn't be more grateful for being able to share every step of it with you.' As a long-term pal and as someone in the same industry as her, she's got a good chance of being in the bridal party.
3 of 11Princess Charlotte
As the niece of Prince Harry, it would be a pretty adorable touch if Princess Charlotte was included in the bridal party. After all, she was part of her aunt Pippa Middleton's wedding earlier this year to James Middleton, so it's not like she hasn't had any practice.
4 of 11Jessica Mulroney
As well as being her unofficial stylist, Jessica Mulroney is also one of Meghan's closest friends, after the two met when the actress relocated to Toronto to begin filming Suits. She is heavily present on Meghan's Instagram account, as is her daughter, Ivy, so we think it's highly likely that she'll have a role.
5 of 11Lindsay Roth
The front-runner for maid of honour is almost certainly Lindsay Roth, who chose Meghan for the same role at her own wedding last August. The Suits actress and producer and author have been friends for 15 years, with Lindsay recently telling People magazine that Meghan is 'the same girl I met years ago'. The two met at a Toni Morrison literature class during their first year of college at Northwestern University.
6 of 11Priyanka Chopra
Another actress that Meghan is good friends with is Priyanka Chopra, who she met at a dinner celebrating women in Hollywood a few years ago. After Vanity Fair ran their cover story with Meghan pegged to her relationship with Prince Harry, Priyanka defended her friend, saying she was more than just 'Harry's girlfriend'.
7 of 11Kate Middleton
As Meghan is marrying into the royal family could Kate Middleton be one of her bridesmaids?We don't know much about how close the women are but they're soon to be family so we reckon they're fairly friendly. PLUS it's going to be a royal wedding so we're pretty sure Kate (who we're guessing will be heavily pregnant) will have a role in the big day.
8 of 11Abigail Spencer
If you're a fan/watched Suits then you'll remember Harvey's ex-girlfriend Scottie (who is played by Abigail). She may have left Suits a few seasons ago but it turns out Meghan and Abigail are pals outside of the TV series. Could we see a Suits reunion on the big day?
9 of 11Sarah Rafferty
If you've ever watched even a clip of Suits then you'll of course know who Donna is.Sarah, who plays the infamous character, and Meghan are close friends in real life so will we see Sarah hold the princess-to-be's dress as she walks down the aisle?
10 of 11Olivia Palermo
Actress and model Olivia Palermo and Meghan Markle are pals too!You may recognise Olivia from The Hills spinoff show The City. As they're both fabulous, famous and friends, we wonder if we'll see Olivia at the big day in spring.
11 of 11Millie Mackintosh
Yup.We bet you didn't know Meghan Markle and Made in Chelsea star Millie Mackintosh are friends?!If you've had a good old stalk on Meghan's Instagram account you'll see this adorable photo of the pair bike riding together.You know, as you do.Will we get to see the former reality star at the royal wedding?
