Prince George looks exactly like dad Prince William at Princess Charlotte's christening

Much like his style-icon mom, the Duchess of Cambridge, Prince George always makes a splash when he steps out, and at Princess Charlotte's christening on Sunday (July 5) he had fans doing a double take.The little royal looked the spitting image of dad Prince William when he attended his brother's baptism in 1984.

George had hearts melting around the world as he arrived in a white smocked shirt with red embroidered detailing and red shorts – an outfit almost identical to the one that Prince William wore when he first met baby Prince Harry in 1984.

Royal fans were quick to note the similarities between the outfits, prompting speculation that the little royal was wearing his father's original look. However, the adorable ensemble is actually a creation by London-based designer Rachel Riley, featuring slight differences including white buttons on the shorts and a different embroidery pattern. The traditional two-piece smocked set costs $166 (CAD) and is available in four sizes on the designer's website, or can be pre-ordered.

Little George was the spitting image of his father in the sweet ensemble, as he walked hand-in-hand with William, looking slightly bemused at the crowds of cheering fans. The young prince seemed quite transfixed with the excitement as he walked alongside his mother the Duchess, née Kate Middleton, who was pushing Princess Charlotte in a pram.

No doubt the smocked set is likely to sell out very quickly following George's appearance at the christening. Like his mother, George always causes a spike in sales when spotted in his adorable outfits, with the industry dubbing his sartorial influence 'the Prince George effect'.

Most recently Charlotte's older brother caused Crocs' Crocband shoes in navy to sell out after he wore them for a day out at the polo with the Duchess.

" Since the HRH Prince George was spotted wearing Crocs’ Crocband shoe in navy, our size 2 sold out immediately!" Crocs' UK & Ireland Country Manager Scott Lucas told HELLO! Online. "The shoes have since become a best-seller, thanks to what we’re calling the ‘Prince George effect’."

" The pictures of Prince George in his Crocs were everywhere, from the UK to America, and Australia to France” added Scott. "It was fantastic to see and obviously everyone at Crocs is happy to see Prince George wearing the shoes!"
