Kate Middleton's Iconic Engagement Dress Goes On Sale Again, Then Immediately Sells Out

Bad news, Kate Middleton fans.
The Kate effect is in full-force this morning, after the Duchess of Cambridge's iconic Issa ‘Phylis' engagement dress briefly returned to Harvey Nichols' shelves, then almost instantly sold out. The sleek royal blue number—which was only available in a darker navy hue this time around—rang in at a whopping $900, meaning that the folks at the British retailer are probably breaking out into a happy dance right about now. Kate first donned the sleek jersey dress back in November 2010, when she and Prince William first announced their engagement.
