The innovative House Maison Martin Margiela launched their Pre-Fall 2013 collection!! The pictures were shot in front of a glass wall, where you can see what is probably the outside terrace of the House.  You can also see the employees, in many pictures, wearing long white lab coats, the official uniform for the personnel.
