Oct 24 2012 If you needed more evidence that wearing Maison Martin Margiela takes a certain kind of confidence, here it is: a hair necklace. Part of the Maison Martin Margiela collaboration with H&M, the piece comes in blond, brunette, and black varieties (sorry, redheads). Longtime fans of the Belgian design house will remember the original versions from years ago, but at $13, the new version is far more accessible — if only in price. It lands in H&M stores starting Nov. 15. If you're planning to shop this exclusive collection, will this lock of hair be on your to-buy list?
