While a fashion show in New York Tuesday night showcased the upcoming Versace for H&M line, a website in China has been claiming to offer the collection online.

On November 8 models including Daphne G, Natasha Poly and Lindsay Wixson showcased pieces from the range at a special launch.

The upcoming partnership evokes various key styles from the Versace archive including silk-crêpe dresses, multi-colored panel print gowns and the classic studded leather jacket.

Chinese online media company Sina, mainly known for its Twitter-like Weibo microblogging service, launched Sina Luxury on Friday.

The new e-store enables designers to sell their collections directly to customers. Those who have already signed up include highest-profile Western brands such as Dior, Burberry, Gucci, and Paul Smith, all “100 percent guaranteed genuine”.

Sina Luxury’s main rivals on the Chinese market are the luxury e-tailing start-up IHaveU.com, which as opposed to Sina also sells menswear, as well as a new fashion store called Netease and e-commerce giant Taobao’s TMalls.

Less than a month after announcing its partnership with Italian designers Dolce & Gabbana, e-tailer Yoox has said it is readying an online destination to shop all of Armani’s ranges under one virtual roof.

The new armani.com Online Store “Powered by YOOX Group” will be launched in the second half of 2011.

Armani.com will be mainly active in Europe, the US, Japan and China, and will feature the Giorgio Armani, Armani Collezioni, Armani Junior, EA7, Emporio Armani and Armani Jeans brands.

Stella McCartney has relaunched her website, equipping it with all the latest features before the fashion week rush. She is also launching a new iPad app.

Almost 30 European countries including France, Germany, Italy, and Spain were added to McCartney’s new e-commerce, which also enables shoppers to reserve an item online and pick it up at a store of their choice.

Additionally, the in-store “Private Wardrobing” service, a personalized concierge service, can now be booked online.

Following Balenciaga and Dolce & Gabbana, Jean Paul Gaultier is the third major fashion brand to present a new website this week.

The new online destination is divided into three sectors: LIVE! integrates social media sites Facebook, Twitter, and YouTube, updates from bloggers, videos and photos from fashion shows as well as news surrounding the brand, while a digital showroom and an e-shop let you browse and buy all collections.
