Meghan Markle and Kate Middleton are living fashion icons.

The royal sisters-in-law may not have personal Instagram pages, but they’re some of the biggest fashion influencers in the world. According to style search engine Lyst, every time Meghan or Kate steps out in something new, they instantly cause a sensation for shoppers hoping to emulate the royal style.

Both Meghan and Kate’s influence reached a peak in March. Kate’s most enviable look came when she wore a red coat by go-to brand Catherine Walker for Commonwealth Day services at Westminster Abbey. Online searches for similar dresses instantly doubled, going up 225 percent.

And before going on maternity leave and welcoming son Archie, Meghan wore a silver and gold brocade dress to celebrate the 50th anniversary of Prince Charles‘ Investiture at Buckingham Palace. The demand for brocade dresses rose a whopping 500 percent online in the day that followed.

Kate’s outfit choices lead to a 119 percent average increase in online demand in the week following a public appearance, while Meghan’s fashion drive demand up an average of 216 percent, according to Lyst.

But the royal women are influencing in different ways. While Kate’s most talked about ensemble choices usually send fans searching for the specific brands, Meghan’s closet drives demand for the colors she wears. White, beige and navy — all favorite shades of hers — boosted the most search traffic.
