Meghan Markle stuns in pleated shirt dress in picture on her 37th birthday

Meghan Markle just celebrated her first birthday as a royal, turning 37-years-old attending a romantic occasion with her husband Prince Harry.

The Duke and Duchess of Sussex attended the wedding of the Prince's friend, Charlie van Straubenzee and Daisy Jenks, who tied the knot last Saturday afternoon in the village of Frensham, southwest of London.

While Meghan had a small wardrobe malfunction while at the wedding, she definitely stole the show in her dark blue dress. While waving to their well-wishers who sang her "Happy Birthday", the Duchess accidentally flashed her bra.

Lucky for her, the bra matched her $700 dark navy Club Monaco dress, which featured colorful lilac, pink, and green trimmings on it. To accessorize her look in the classic British way, she sported a fascinator by Philip Treacy.

When she noticed the malfunction, she quickly adjusted her dress and continued waving at their supporters who gathered outside the ceremony at the St. Mary the Virgin Church in Surrey.

Harry and the groom Charlie have been good friends since preparatory school, and the prince served as his best man. Braving the hot summer's day, the handsome prince sported a morning suit, pinstriped trousers, a blue waistcoat, and a long jacket.

Due to the duke's best man status, the royal couple arrived separately, with the 33-year-old joining the bridal party and his wife arriving shortly after with a group of women.

According to News AU, Markle's birthday falls on the same day as the late Queen Mother, who was born on August 4, 1900.

The way the couple celebrated Meghan's birthday is a lot simpler this year, as they went on a private getaway to Africa to celebrate her 36th birthday, which came before they announced their engagement.

Miss Markle was welcomed into the Royal Family on May 19, when she married Prince Harry at the St. George's Chapel at Windsor. Just like how Harry was his best man, Charlie van Straubenzee was also one of the Duke of Sussex's ushers during his own special day.

Happy birthday, Princess Meghan!
