Here is a great post from the New Yorker Magazine Blog - The Cut on Kate Middleton's Wedding Dress
Thankfully, the rumors were true: Kate Middleton's wedding dress was designed by Sarah Burton of Alexander McQueen. Fashion critics are pleased. The Telegraph's Hilary Alexander raves: "Fabulous, fashionable and fairytale, the dress was fit for a queen-to-be and combined the style of a modern princess with that of a 20th Century princess." Vogue deems it "technically faultless in its scale and construction," noting that it "allowed the bride to move with ease, carrying all the weight of British history and expectation without the slightest wrinkle or hitch." Other critics noted its resemblance to dresses worn by Grace Kelly and Queen Elizabeth II. Karl Lagerfeld chimed in on France 2 television, saying, “She is very elegant. The dress is classic and goes very well in the Westminster decor. It almost reminds me of (Queen) Elizabeth’s wedding, the royal weddings in the Fifties. The proportion of the train is good."
Non-critics were less impressed, according to the Times' Christine Haughney.
Daniel Orszewski, a 31 year old head of styling for Top Shop, leaned back in his booth at G-A-Y Bar, sipped champagne and expressed his concerns about Ms. Middleton's fashion choice saying that the dress was too plain.
"I thought Pippa looked better," he said while dressed in a tight black Union Jack t-shirt. "I thought the lace looked too fussy. The overlay on her head looked like a curtain."
WWD polled several designers. Hubert de Givenchy said: “The dress is very simple and very nice. The veil is a little flat, but because she has such a lovely face, she can afford to wear it this way. She is very pretty.” Christian Lacroix noted approvingly that the dress was "simpler than expected," while Elie Saab was a bit more critical: "I would have liked it even more with a little extra volume and a longer train.”
