In a statement, Vogue's famous editor-in-chief Anna Wintour called McQueen "one of the greatest talents of his generation...In such a short career, [his] influence was astonishing - from street style, to music culture and the world's museums. His passing marks an insurmountable loss."
Designer Philip Lim told UsMagazine.com in Bryant Park Thursday, "I'm speechless. It makes me ill. If anything positive can come out of this, we should take the moment to appreciate what we have, what we do...I love what I do, and I should be damn appreciative that I can still do it."
