Meghan Markle and Kate Middleton are fashion icons whose clothes sell out almost immediately - here are 13 of their favorite brands

After Markle wore this sweater from the Victoria Beckham collection, which is available at Nordstrom, it sold out nearly immediately online.

This Strathberry bag sold out online seconds after Markle was seen carrying it. It has since been renamed "The Meghan."

The same day, she wore the Elodie coat by Mackage. It sold out within hours of the photos of her wearing it were released, but it has since been restocked.

Markle wore this now sold-out Stella McCartney coat while visiting Cardiff Castle in Wales with Prince Harry.

One of the few items that didn't sell out immediately after Markle was seen wearing it was this Wolford body suit, which costs $250.

At the Invictus Games in September, she wore Everlane's $68 high-rise skinny jeans and carried the brand's $165 brown leather tote. The same day, she wore Sarah Flint's Natalie Flats, which are just about sold out.

This $140 Topshop dress sold out almost immediately after Middleton wore it while visiting India.

Middleton is known to wear Jenny Packham designs, making the brand a go-to for celebrities.

She also wears Temperley London quite often, and the dresses she wears from the brand frequently sell out.

Catherine Walker is another one of the brands Middleton repeatedly wears.

Middleton was spotted in this pink Mulberry coat in December 2014, causing it to sell out online.

She has also been spotted wearing Reiss dresses, like the "Shola" dress above. After she wore it to a White House occasion in 2011, the Reiss website crashed as fans tried to buy the dress for themselves. The style was later discontinued.
