Now that the fuss has died down somwhat; can I add my opinion?
The dress was exactly what a girl like Catherine should have worn-A "commoner" (how I hate that word) being elevated to the status of a Duchess-it was a dress you might find in any country church-made different by the excellent tailoring, the stuff it was made from, and attention to detail-and that essentially, is the difference between a Simplicity pattern and a Couturier. It suited her, she looked lovely.
As far as the Grace Kelly likeness-it had a lace bodice-otherwise-not really. Helen Rose designed Grace Kelly's gown, and it is interesting to note that she also designed the dress for Elizabeth Taylor's wedding to Nicky Hilton, a couple of years earlier-lace bodice, tight sleeves, full silk skirt. very 1950's- and that to my mind is where she (H Rose) got the inspiration for G Kelly-but pared down for Kelly's taller more slender frame-and where the inspiration for the Royal dress came from-If you go to the Vogue Vintage pattern site for the 1950's you will see many, many designs that draw on that design of Christian Dior's "New Look"-made famous by the likes of Audrey Hepburn Lauren Bacall Grace Kelly(think "Dial M for Murder") and Princesses Elizabeth and Margaret, in the 50's, as well as the Dior house models. Perhaps that's what Sarah Burton wanted...A "New Look" for a new princess.
I hope that Catherine has put an end to the strapless bridal gown-so naff! so crude,so inappropriate.
I have heard she went from a size 10 to a size 6 in the last month or two-no wonder she looked tired and drawn-and the makeup for TV wouldn't have helped. Let's hope she rests and regains her "freshness" she is a very attractive young woman. He's a lucky fella-
And...Harry doesn't walk, he swaggers.....I guess I would too!!
