Unsurprisingly the "Kate effect" has struck again. Online retailer eBay reported that U.K. sales of yellow dresses increased by 58 percent right after the Duchess was pictured in her buttercup print Jenny Packham dress, according to The Independent. Australian eBayers got even more excited about her choice of frock; sales there soared by 208 percent.
The same thing happened during the 2014 royal tour of Australia and New Zealand when the Duchess wore two different yellow dresses in two days, sending eBayers into a frenzy and hiking yellow dress sales up by 93 percent.
And the blue Issa dress Kate wore for the official announcement of her engagement to Prince William in 2010 sold out within 24 hours, inspiring numerous high street copies and starting a trend for "little blue dresses."
Kate isn't the only one in the family to influence shoppers; eBay has also revealed that sales of blue cardigans for little boys have increased by 128 percent after Prince George was photographed going to meet his baby sister in a blue outfit.
The dress Kate chose to wear when she introduced Princess Charlotte Elizabeth Diana to the world is bespoke, naturally, but there are plenty of (cheaper) alternatives if you fancy stepping out in sunny yellow this season.
