Trend Alert! Celebs Class Up Red Carpet with Royal Blue

One of Kate Middleton’s first contributions to the style world was after she stepped out in a royal blue Issa dress this past fall to announce her engagement plans to her now husband Prince William. Now the color is showing up all over the red carpet, as well as on Kate’s sister Pippa and Prince Harry’s on-again, off-again girlfriend Chelsy Davy.

As for the dress that started it all, London based designer Issa was Kate’s go-to, because she loves simple wrap dresses and sexy-chic evening gowns. So it was no surprise when she stepped out in an elegant royal blue getup to match her new sapphire engagement ring. 

The dress was such a hit that it sold out within 24 hours from British retailer Harvey Nichols! “Since the announcement of the royal engagement we have been inundated with requests regarding Issa,” Harvey Nichols’ buying director Averyl Oates told British Vogue back in November. The dress was priced at $600 American dollars, and, according to Averyl, “sold out almost immediately.”

However, Kate also caused a bit of a style stir prior to her engagement. In 2007, the Duchess wore a Topshop dress to her 25th birthday party, and that dress was also sold out within 24 hours of being photographed.
