We get a lot of messages from customers about the product will continue to be produced? So , we have set up a pre-order system and the product will be in stock in a few weeks. It is the brand’s best-selling royal item ever.” Not only Princess Charlotte is noticed for her fashion sense, Prince George has also attracted the attention of the press many times thanks to simple and dynamic outfits. The proof is that Cath Kidston’s vest and shorts, worn by the prince at Christmas when he was 16 months old, quickly sold out. In celebration of Queen Elizabeth II’s 90th birthday, the prince’s red shirt and shorts also became Rachel Riley’s third best-selling item. Prince George’s outfit is loved by many. Photo: Daily Mail.
