The site will offer more than 200 luxury fashion brands including labels such as Chloé, Oscar de la Renta and Christian Louboutin at discounts of between 40 and 60 per cent.
Stephanie Phair, previously vice-president of merchandising at luxury auction website Portero, will head the venture.
In an interview with WomensWearDaily, Net-a-Porter founder and chairman Natalie Massenet said the launch was not just a reaction to a challenging economic climate and that Net-a-Porter has always had a “very high sell-through” in its Sale shop.
She said: “When we do come out of this current crisis, theOutnet will still be relevant. This is really about the lifecycle of fashion, and for us there are good margins to be made.”
