Princess Charlotte has become an overnight style icon at six years old.
Vanity Fair reported that the floral dress she was pictured in for her recent birthday post has sold out.
The Rachel Riley dress, which retails at £5 (around R100 at the time of publishing), has sold out, according to Rachel. But it will be back soon, she said.
"It was such a treat to see Princess Charlotte wearing our button front floral dress to mark her sixth birthday! She looks so happy in the picture," Riley, who owns the upscale boutique, said.
The designer has "no doubt" Charlotte will become a fashion influencer just like her mother, who is known for the "Kate Effect," which refers to the trend effect she has on others.
