High street brand H&M

Pieces from the Maison Martin Margiela with H&M collection are available on eBay.

The designer-high street collaboration isn't due to arrive in stores until November 15, but an unknown source has secretly posted some of the items from the 105-piece collection for sale online.

The recommended retail prices have been inflated by the fashion bandit in order to cash in on the hotly-anticipated collection's success.

The £179.99 duvet coat is currently on sale for over £235, while the mirror ball leggings (£29.99) are available for more than £65 and bids for the silver candy clutch (£34.99) are exceeding £135.

H&M hosted a star-studded launch party for the line in New York on Tuesday (23.10.12) and one or more guests are thought to be responsible since they were the only people given early access to the clothes.

The items have been posted online from the US, Vogue.co.uk is reporting.

H&M's previous designer collaborations, including Marni, Versace and Lanvin, were cleaned out within minutes of going on sale.

They proved popular on eBay and online auction sites as people sold them on to fellow fashionistas.
