Issa WHO? Kate Middleton wore a cream dress by British label Reiss that is no longer in stores for her official engagement portrait with her fiancé, Prince William. The Daily Mail believes the dress cost £159, or about $250, and reports it was part of the last fall collection. For the other shot, in which she flaunts her sapphire engagement ring on William's pec, she wore an embroidered blouse from Whistles that costs £95, or about $150, and was still available in the store yesterday. Her $550 Issa dress remains pretty much impossible to buy, though you can register interest in the frock on Net-a-Porter.
By choosing things that are nice but not out of this world, fashion-magazine-expensive Middleton is positioning herself not dissimilarly to Michelle Obama, who famously wore J.Crew and H&M during Barack Obama's campaign. Middleton hasn't gone as cheap as those stores yet, publicly, but she has plenty of time to frolic about in that sort of thing before the wedding upsets those Brits who don't want their tax dollars to be any part of it. She and the prince have said repeatedly that they want to make it a modest affair (hahaha), considering These Economic Times.
As for Prince William, he also wore clothes for the photo, which were designed by someone.
