I first fell in love with Yves Klein Blue at a Zara in Milan. I bought the sweetest pair of blue flats in this unique hue when i was there in 2006. I love pairing my flats with neutral tones or my Saturday uniform of jeans and a JCrew tshirt. When I bought these Zara flats I had no idea that their color was called Yves Klein blue and I just referred to them as cobalt. Regardless of what you call this color, it is striking and will be a major trend for Fall 2011. Here is how some designers infused this blue into their fall runway shows.
