It seems Princess Charlotte's royal wardrobe won't include a lot of dresses — at least until she turns one-year-old!
"Because they're a traditional family, I'm sure that she'll wear [onesies] for the first year, and then only when she's walking will she then move into dresses," Kate Middleton's go-to children's wear designer, Rachel Riley, told [People](http://www.people.com/people/package/article/0,,2039522220954443,00.html)_ in a new interview.
"Even in terms of separates, I don't think she'll be wearing separates until much later," Riley added.

One exception to this royal rule was, of course, the gown Charlotte, 4 months, donned for her christening in July. For the occasion, the little one wore a replica of the royal christening gown first worn by Queen Victoria's daughter in 1841.
Despite not wearing dresses during her first year, Charlotte and her older brother, Prince George, 2, are still some of the world's biggest trendsetters in children's clothing. "They are absolutely trendsetters," Riley said of Kate and Prince William's kids. "When you look at them, they’re just gorgeous, their clothing is gorgeous. The royals stay relevant and modern."
