Chadwyck-Healey, 36, better known as Ginnie, and her husband Oliver attended St. Andrews University with Kate, 37, and Prince William, 36. They were guests at the 2011 royal wedding at Westminster Abbey, where she wore an Emilia Wickstead watermelon pink skirt and a bubblegum pink trapeze-sleeve silk top.
"To my great surprise, I found myself included in the fashion reviews as one of the "best-dressed wedding guests," Ginnie boasted.
Ginnie, who served as the former editor at Vogue magazine for twelve years, temporarily replaces Kate's stylist Natasha Archer, while she is on maternity leave.
As Radar readers know, tension has been brewing between Kate and Meghan.
Meghan, 37, was accused of making Kate cry at a bridesmaid fitting before her wedding to Harry, 34.
Radar also reported that Meghan and Harry were not only leaving William and Kate's abode, but were looking to "split their staff in an effort to ease tension" between Kate and Meghan as well.
Now, Kate is dumping the dowdy duds to look as modern as her former actress sister-in-law!
