"High-level glamour is becoming more of the norm for Kate due to her role," her stylist pal Nikki Pennie, Editor-at-Large of StyleHaul, told People. "She is becoming more playful, putting her hair in gorgeous updos to complement certain dresses. She is clearly enjoying the process and becoming more confident."
Kate reportedly does everything herself, from her own makeup to picking out her own clothes -- rather than accepting gifts from designers and the like.
"She is becoming more and more confident, which I think is exciting to see," said Stewart Parvin, a couturier to the Queen. "The way she does her hair, the way she does her makeup is getting better and better, and she has this new inner glow."
