Neither of the York girls seems to have rebelled. Remember Zara with her tongue piercing ?
Kate's style has evolved from her mother's (in the early days she wore some of her mum's outfits). I wouldn't say Kate's style was ever Sloaney ( read garish) Remember the duchess of Westminster in the orange & zebra print dress.
On formal occasions; Kate dresses a bit like a young Queen.Elizabeth from the 1940s.
Speaking of retro, Meghan looked amazingin that dark blue Dior dress st the RAF thing.
I cannot wait for Eugenie's wedding. It is going to be a fashion feast (both good and bad'!)
