Nothing – not even economic chaos – can keep Net-a-porter down. For the fourth successive year, the online luxury goods retailer makes an appearance our Hot 100 list. Net-a-porter proudly describes itself as “the world’s premier online fashion retailer” and, with sales of £55m in 2008, it’s hard to cavil with the description. The key to Net-a-porter’s phenomenal success is its full-colour online magazine, which describes and illustrates all aspects of the womens’ fashion wear it sells. Stocking clothes from 200 top designers and shipping to more than 170 countries, Net-a-porter is the brainchild of French fashionista Natalie Massenet – no surprise given the French reputation for being trés chic.
