Princess Charlotte is undeniably one of the youngest fashion icons in world. Royal watchers and fashion conscious mothers have been looking out for the royal baby’s cute ensembles and other accessories that her equally fashionable mom, Kate Middleton, has chosen to use. For fans curious about Princess Charlotte’s royal dress code, fashion designer Rachel Riley shared some of her insights on the royal baby’s first year fashion.

Riley is a children’s wear fashion designer and Princess Kate’s go-to label for her daughter’s cute outfits, including Prince George’s. Riley revealed to People magazine that Princess Charlotte won’t be wearing dresses until she turns one year old. "Because they're a traditional family, I'm sure that she'll wear babysuits for the first year, and then only when she's walking will she then move into dresses," Riley said.

Apart from this, Princess Kate is said to favor one piece babysuits over two piece outfits. Riley explained that the royal mom would most likely use separate pieces until Princess Charlotte is a little bit older. The designer said, "Even in terms of separates, I don't think she'll be wearing separates until much later."

Meanwhile, Prince William and Princess Kate’s two children have become fashion movers and even managed to contribute to the economy at their young age. A report from Brand Finance released earlier this month indicated that Princess Charlotte has contributed nearly $5 billion to the British economy, CNN reported. Prince George, on the other hand, has an estimated contribution of $3.6 billion.

The royal baby’s “Charlotte effect” fashion brands and other baby items have helped push demand up for pieces that the little princess used or wore. Since her birth, such transactions reportedly generated more than $150 million, according to Brand Finance estimates. One of the pieces that became popular because of the “Charlotte effect” was the GH Hurt $100 lacy shawl that Princess Kate’s daughter wore when she was first introduced to the world, and the vintage pram that was used during the royal christening.

There’s no doubt that Princess Charlotte and Prince George are already following their famous mother in becoming fashion trendsetters.
