Kate Middleton’s favorite children’s clothes designer talks about inspiration behind outfits worn by Duchess’ son

The Duchess of Cambridge’s son, 2, stole the show with his cuteness at his little sister Princess Charlotte’s christening last month, as he wore a traditional Rachel Riley two-piece, an imitation of Prince William’s outfit when he met his brother Prince Harry for the first time, in 1984.

Designer Rachel Riley talked with The Mail on Sunday in July about her sources of inspiration, revealing that she finds the late Princess Diana’s choices inspiring, in terms of the way she dressed up William and Harry when they were little.

“I look at old pictures of William and Harry as boys because the outfits are beautiful and a wonderful inspiration,” Riley told the publication. “Princess Diana had a great sense of style. She was a nursery teacher so was a natural with children and knew how to dress them. She dressed William and Harry in clothes that are appropriate for children.”

She added, “They were comfortable and classic and, being from a traditional family, I think Diana understood the need for the Princes to be properly dressed. Diana loved fashion and she wore everything so well.”

Also, Kate Middleton’s son wore a Rachel Riley set, consisting of a shirt and shorts, in his sister’s first portraits. The pictures were taken by the Duchess, 33, who is passionate about photography.

Earlier this month, the children’s clothes designer, whose other famous customers include Beyoncé, also talked with People magazine about the “Prince George Effect.”

“We sold out on the same day and have re-ordered three times, just to satisfy customer demand,” the British designer eaid, referring to George’s attire worn at Princess Charlotte’s baptism. “Everything he wears is so popular.”
