If you’ve seen Lagerfeld Confidential, you know that Karl is never one to shy away from a motocross look—Sons of Anarchy via Chrome Hearts and leather pants, with the chopper on the side, thanks. So it comes as no surprise that he’s teamed up with Les Ateliers Ruby for the fourth installment of their limited-edition helmet series.

Following Maison Martin Margiela’s artful defacements, Karl is giving the protective headgear the ultra-luxe makeover. First appearing on Karl’s runway for fall, multiple versions are finally hitting stores, including a lady-like helmet in black and white tweed (a subtle nod to Chanel) and a couture-ish one embroidered in pearls. But the most obscenely luxurious headdress has to be the one covered in lustrous black mink—part urban barbarian, part futurist warrior.

€1200 – €4545 at Colette and select retailers in December. With only 12 made, rest assured no one else will ride up with one at your local biker bar.
