Duchess of Cambridge Kate Middleton travelled by car to the Queen’s 70th anniversary celebrations at Windsor Castle.
Sitting in the back seat of the car, Kate, who is pregnany with her third child, wore a black textured high necked lace dress with a sweetheart neck.
The dress had long sleeves in a more sheer lace design which showed off Kate’s long slender arms.
She accessorised with pearl drop earrings that delicately framed her face and jawline.
Around her neck she wore a stunning necklace made from several strands of pearls, and fastened in the middle with a diamond clasp.
Smiling at her husband Prince William as he looked on, Kate looked radiant, natural and relaxed.
The glow extended to her complexion, which was luminous and brightened by a blush spreading across her cheeks.
Her hair had a lustrous shine and was curled back away from her face, the waves highlighting the subtle caramel tones in her hair.
Her eyes were framed with black eyeliner and a chocolate brown shadow, while her brows were immaculately groomed.
Prince William wore a black tie suit, including a black bow tie and a white silk pocket scarf.
He looked forward calmly with a slight smile on his face, as if listening to a joke from Duchess Kate.
Sitting on Kate’s other side, Harry – also in a black jacket and bow tie – looked out of the window, his arm resting on the door.
While William is clean shaven, Harry’s auburn beard is immaculately clipped for the occasion.
Kate’s dress looks very similar to one she wore to the Anna Freud Gala Dinner earlier this month.
If it is indeed the same one, it is a floor length black Diana Von Furstenberg dress.
The material flatters Kate’s lithe figure, while allowing for her pregnancy bump to be comfortable.
The Duchess also wore this same dress back in 2014, when she was pregnant with Princess Charlotte.
