When Kate Middleton's engagement photos were released, her blue Issa dress made the brand more popular than ever before. Her trusty L.K. Bennett pumps? Women bought them. And that $35 Zara necklace easily sold out.

Now, Middleton is influencing dress length, with shoppers avoiding minis.

"And eBay has revealed that after news broke of the Queen's request for less-leggy outfits from Kate, the site tracked a 30 percent decrease in popularity for fashion searches for above-the-knee dresses," according to an International Business Times article.

The retailer also created an appropriate GIF of Queen Elizabeth II lowering the Duchess' hemline by hand.

A collection created by phoebe-occ and called The Kate Effect said, "New rule: short skirts are out...So today we invite you to go long for Kate, with this collection of more modest looks."

There is not a knee in sight in the 15-item collection.

Earlier this week it was announced that for Middleton's upcoming trip to Australia, she would be dressed in more modest attire. She's rebranding after the birth of her son, Prince George.

Though Middleton loves frilly dresses, as evidenced by her engagement photos, she has revealed a bit too much skin on more than one occasion when gusts of winds have blown her skirt up. One of the times was at a charity event.

Consumers can easily make the switch to longer hemlines, but they likely won't follow her on the second part of her makeover.

Middleton is also getting an upgrade when it comes to jewelry.

Angela Kelly, who has been tasked with updating the Duchess' wardrobe, "has been asked to start selecting jewels ahead of the trip. She knows most of the pieces in the Queen's private collection. Her understanding is crucial because this trip will be about Kate appearing more Royal than ever - you can expect to see a lot more tiaras and the Queen will be watching closely."

Then again, maybe women will just wear more crowns.
