Lady Amelia Windsor wears head-to-toe Chanel at the Queen's service of thanksgiving

Though Lady Amelia Windsor is a lesser-known member of the royal family, she's no wallflower. While at St Paul's Cathedral on Friday (June 10), the blond beauty proved herself one to watch in the style department with her flawless ensemble.

Amelia was one of 53 royals to attend the Queen's Service of Thanksgiving and stole the show in a chic Chanel ensemble. Her black shirt-dress featured a pleated front with fluted tweed sleeves and bow detail, and was paired with pearl-embellished black strappy heels and a black-and-white hat.

The 20-year-old is quickly capturing the attention of the fashion world with her sartorial know-how and sat front row at the Christian Dior SS17 Cruise collection show at the end of May.

Amelia was joined by her sister Lady Marina Windsor

Named Tatler magazine's 'most beautiful member of the royal family', Amelia arrived at Friday's service with her older sister Lady Marina Windsor, who donned a tweed skirt suit and black fascinator for the special occasion.

They were not the only stylish siblings at the church service; Princess Beatrice and Princess Eugenie also turned heads in their high-fashion ensembles. Beatrice wore a $5,473 monochrome embroidered Burberry coat and co-ordinating hat by couture milliner Sarah Cant, while Eugenie opted for a $2,650 red dress with a cut out neckline from Eponine.

Joining the royal party was the Duchess of Cambridge, who was the epitome of elegance in a pale-blue dress by one of her favourite designers, Catherine Walker.
