Meghan Markle dress REVEALED: First picture of Prince Harry’s bride on wedding day

The radiant bride flashed a quick smile as the world caught a glimpse of the dress royal watchers and fashionistas had had been waiting for.

The wedding dress has been kept a heavily guarded secret, with the creators working behind blacked out windows and sworn to silence.

Wearing a veil and tiara, Meghan beamed as she sat next to her mother. 

Meghan's dress features a boat neck style and she appears to be wearing the Queen Mary Tiara Bandeau - The Filigree Tiara - on loan from the Queen.

Huge crowds lined the Long Walk to Windsor Castle as the Rolls-Royce made its way escorted by three Range Rovers.

Well-wishers cheered and waved flags as the car passed, before making its way through the gates on its way to the chapel.

The first glimpse of Meghan's dress has revealed an "elegant and sophisticated" choice, a commentator has said.

Aruna Seth, shoe designer and socialite, said the boat neckline on the white dress was "modern" complemented by traditional long sleeves.

Ms Seth, who designed Pippa Middleton's shoes for the wedding of the Duke and Duchess of Cambridge, said: "The veil looks very traditional and as I expected and her hair up looks gorgeous in a low bun."

"Very elegant and sophisticated."

When asked how it compares to Kate's dress, she added: "Looks more simple and the boat neck is very modern, traditional long-sleeved."

The first glimpse of the bride's gown was seen as she travelled to St George's Chapel in a vintage Rolls-Royce limousine, loaned for the day by the Queen.

Wearing a white veil and white dress with a boat neck she waved to onlookers as the car departed.

As Meghan and Doria make their way to Windsor Castle, Princess Beatrice and Eugenie and senior members of the Royal Family arrived at the church. 

Meghan sat in the rear of the car with mother Doria Ragland.

Wearing a white veil and white dress with a boat neck she waved to onlookers as the car departed at 11.19am.

The bride travelled to St George's Chapel in a vintage Rolls-Royce limousine, loaned for the day by the Queen.

Meghan and her mother Doria Ragland left the Cliveden House Hotel in the Rolls-Royce Phantom IV, which was built and delivered to the Queen and the Duke of Edinburgh in 1950 when she was still Princess Elizabeth.

The Duchess of Cambridge used the same model for her trip to Westminster Abbey for her wedding in 2011.

Royal fans caught a glimpse of the dress, but were eagerly awaiting to see the gown in all its glory.

Meghan will be joined by six bridesmaids and four page boys – including her future niece and nephew Princess Charlotte and Prince George.

Meghan and Harry will say their vows before the Archbishop of Canterbury The Most Revd and Rt Hon Justin Welby.

Both Harry and the Duke of Cambridge are wearing the frockcoat uniform of the Blues and Royals.

The Queen gave her permission for her grandson to get married in his uniform, Kensington Palace said.

Harry looked relaxed as he walked down to the chapel with his brother, the Duke of Cambridge, to loud cheers from the waiting crowd.

The pair smiled and waved to well-wishers during the short walk.

Both uniforms were tailored at Dege & Skinner on Savile Row.

Cheers and applause erupted at the West Door as Prince Harry and the Duke of Cambridge arrived at St George's Chapel.

The bridegroom and his best man were met by the Dean of Windsor.

They stopped for a few moments and had a brief conversation, before walking inside.

Harry, looking dapper in his frockcoat uniform of the Blues and Royals, walked up the aisle with his best man and was seen acknowledging a guest in the congregation with a nod.

Prince Charles has stepped in to walk Meghan down the aisle after her father Thomas Markle chose to stay in the US due to ill health.

The former Hollywood lighting director suffered a heart attack last week.

Mr Markle has since undergone major heart surgery.

Meghan’s mother Doria Ragland arrived on Wednesday to help the bride prepare for the big day.
