It's hard to upstage any baby on their Christening day, especially a future king.
But proud mum Kate Middleton and her glam sister Pippa threatened to do just that as they turned on the style for Prince George's first royal engagement yesterday.
The son of the Duke and Duchess of Cambridge was Christened yesterday in a low-key ceremony at St James's Palace. It was the second public appearance for the three-month old baby since his birth in July.
And it was an outfit fit for a prince as the young royal wore a long cream Christening robe with ruffles and delicate lace.
Keen to keep in line with her son, Kate also plumped for a cream outfit with a ruffle finish, although she kept things modern with a floral, netted hat.
The 31-year-old once again gave a nod to her favourite designer Alexander McQueen as she dazzled in the slim-fitting outfit with a matching hat by milliner Jane Taylor.
Cream was the order of the day with younger sister Pippa covering up in a Trapeze coat and Paris dress by British designer, Suzannah.
The wool frock coat is worth nearly €1,000 and Pippa finished off the look in a pair of dusty pink heels and matching bag.
Prince Charles' wife Camilla, the Duchess of Cornwall, was elegant in an all-cream ensemble while fellow grandmother Carole Middleton plumped for a navy coat.
It was a special day in London with the small ceremony, attended by just 24 people, with four generations of the royal family.
The stylish fashionistas were all in tune with Prince George and ensured their outfits complemented his Honiton lace Christening gown, handed down through the generations. Both families had come together for the private ceremony, which took place at the historic Chapel Royal at St James's Palace.
The Archbishop of Canterbury greeted both families at the chapel.
Prince Harry and Pippa Middleton both gave readings at the Christening.
Prince George will have seven godparents, including Zara Phillips and six of his parents' close friends.
The Christening service lasted around 35 minutes and Philip and the Queen were the first to leave.
She wore a sky blue cashmere coat with a paisley printed silk dress, in moss green and dove grey, by Stewart Parvin. Her matching blue cashmere hat was by Angela Kelly.
And young George's Christening ended like any other – with slices of Christening cake.
