Prince George's adorable Christmas photo vest is already out of stock for the holiday season.

The little prince was pictured laughing and smiling while sitting on the steps in the courtyard at Kensington Palace.

The decorative vest, which was previously sold for $40 on the British brand's website, is still out of stock, but the retailer is looking to bring it back due to "popular demand."

A Cath Kidston spokesman told the Daily News: “Due to popular demand, we are going to look at adding it back into our range of kidswear in 2015.”
