After filing a lawsuit against Yves Saint Laurent in April 2011, Christian Louboutin has engaged in a new legal battle. The designer is now accusing Jessica Simpson of copyright infringement, alleging that her “Evangela” towering sandals are strikingly similar to the “Statarata” model the French designer launched a couple of years ago.

Convinced that numerous e-commerce sites are selling knockoffs of his iconic red soles, the designer has decided to offer customers a way to hunt down counterfeit: an online platform called Stop Fake – Christian Louboutin.

“Keep in mind that when something is too good to be true, that’s usually what it is worth. Websites selling low low priced Louboutin looking shoes (so called “cheap Louboutin”) are probably not selling the real thing. We make no shoes in Asia. There is no factory in China that can sell legitimate shoes to anyone as we do not use any factories in China,” warns the French maison on its site.

The designer explains that a thorough program to fight against retailers selling counterfeit products and the companies providing the fakes was designed to help online buyers only purchase authentic shoes.

Louboutin also outlined that the brand monitors auction sites and their hosting providers and works with customs services to fight against counterfeiting.

Christian Louboutin launched its European online boutique April 11. Customers can shop on the Christian Louboutin website for designs by color, size and heel height — with high and sky high unsurprisingly dominating the options.
