Undisputedly, Kate Middleton has the best taste in fashion and style. The Duchess of Cambridge is the royal ambassador of fashion, grace and beauty for the world.

Recently the Duchess was spotted on King's Road in London shopping at the French Connection. After her visit to the Audio Polo Challenge with Prince William and Prince Harry, Kate bought a French Connection's Winter Silk Vest Top in Iceberg for a frugal £49. On yet another occasion, Kate was spotted browsing high street favourites Jaeger and Anthropologie.

Of late she has been flashing Emilia Wickstead and Jenny Peckhams for social outings. Kate's change to experiment newer choices has led fashionistas to believe that the Duchess is on a wardrobe makeover spree. Apparently, she has been doing a good job managing it all by herself.

"High-level glamour is becoming more of the norm for Kate due to her role. 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. She is becoming more adventurous with her fashion choices. She's always been glamorous, and now even more so," Kate's stylist pal Nikki Pennie, revealed to American magazine People.

"She is becoming more and more confident, which I think is exciting to see. The way she does her hair, the way she does her makeup is getting better and better and she has this new inner glow," Stewart Parvin, couturier to the Queen, told Marie Claire.

The Duchess is forever on the spotlight now that Vogue magazine wants her to grace their cover. But Kate has not accepted the offer and has turned down the similar offers in the past.

"I'd love to have Kate Middleton on the cover. I assure you it is not for want of asking!" Alexandra Shulman, editor of Vogue, told at a Vogue event in London.

Some speculate that she is not accepting the Vogue offer so as to not to upset the Queen.

"Kate is keenly conscious that her new grandmother-in-law may not chide her for appearing on a Vogue cover. Both William and Kate feel it would be wrong for Kate to promote herself as a fashion or style icon. That's not what they are about and they take their royal duties far too seriously to, in one sense, trivialise them," a palace source told E! Online.

According to the Mirror, even though Kate seems to be followingin her late mother-in-law, Princess Diana's footsteps, gracing the cover page of Vogue magazine might take some more time. Diana appeared on the cover page of British Vogue four times. An earlier IBTimes report had analysed the styles between Kate Middleton and Princess Diana.
