Dries Van Noten Was showing Aviator sunwear in his spring summer 2011 runway show. Aviators are a casual sporty look which matched perfectly with casual/formal mixture of jeans with a dressy top. Oversized jackets, drapey coat dresses and tops worked.
Much of the designs were floral inspired, bold fuchsia and purple flowers with an Asian flair.
I would believe the eyewear was a collaboration with Linda Farrow. as you can purchase Dries Van Noten eyewear on her site.
