Prince George looked cute in a John Lewis jacket on his first day to nursery school Wednesday. The blue quilted jacket is by one of Kate Middleton’s favorite stores. It belongs to the high street brand’s autumn/Winter 2013 collection.

Little George’s jacket is already sold out due to the fact that it belonged to John Lewis’s A/W 2013 collection. It featured a detachable hood with brown cord, trendy elbow patches and tartan lining. The third in line to the British throne wore the classic design with a light blue backpack.

Royal fans are now keen to know where the bag is from. As soon as the little royal was spotted with the outfit, mothers all over the world are keen to copy the tot’s royal style. In fact Prince George Pieces Twitter account shared the details of the prince’s jacket.

“George wears a navy @johnlewisretail jacket in the new images taken by Kate!” a tweet from the account read. The British retailer, which has long been the nation’s go-to destination for high quality back-to-school clothing, is a firm favourite of the Duchess of Cambridge. The 33-year-old mother was pictured visiting the store for some last minute shopping just before Christmas.

George’s style has earlier featured old-fashioned outfits such as white knee high socks and embroidered smocks. On his first day at school, George looked like a normal toddler of his age. Some have even suggested that his John Lewis coat could have been a hand-me-down as it is out of stock.

The British store has a similar style without the patches and sales are reportedly likely to rocket if the young prince’s previous track record is anything to go by. In October, John Lewis reported how sales of boys’ navy knitted jumpers shot up 69 percent after George wore one to meet his new sister Princess Charlotte for the first time at the hospital last May.

Besides, sale of red corduroy shorts like those worn by George to Princess Charlotte’s christening skyrocketed in by 60 percent due to the "George Effect."
