London - The world of haute couture is gobsmacked: Kate's white, five grand evening dress topped off 'like a blob of sugarpaste icing on a ubiquitous fairy cake' - by a jaw-dropping fluffy angora cardie.
"It's a classic anorexic/bulimic style-bible fave," Vague Magazine fashion editor Poppy Botox commented, "the little chi-chi Nigella-style cardie with cutesy pearl buttons.
"I call it a throwback to nursery days - along with lace-frill socks and Alice hair bands.
"Just what makes a grown woman of 39 - er...29! - plump for such a garment is beyond imagination!"
The offending sartorial garment clung to newlywed Kate's tan machine-bronzed shoulders last night as fashionistas dissected the evening's bling.
Meanwhile US networks were reporting that the glittery silver belt embellishing Kate's party frock 'was a direct rip-off of Chelsea Clinton's own wedding dress'.
Worried viewers called in complaining that Chelsea's $50,000 Vera Wang bridal confection had been plagiarised.
Pippa Middleton is 5ft 10ins.
