Alexander McQueen's ethereal fall 2012 collection continues to captivate with an equally airy ad campaign shot by David Sims and starring  Suvi Koponen as Sarah Burton's futuristic femme fatale. Echoing the runway's sleek styling and space-age visors, Koponen floats before Sims lens as the two play up the collection's otherworldly beauty. Lovely as always, check out the full campaign in the gallery below.
