For me, I love how a blazer can instantly update a casual outfit and keep me warm like a light jacket. My black boyfriend blazer is a staple in my wardrobe that I wear over jeans. This spring I just picked up the Aqua Girlfriend Blazer in Ivory (pictured left, $98 at Bloomindales). The Aqua line at Bloomies is one of my favorites for it's staple items that are in style with a fantastic price. A white blazer will not only look chic over jeans but they are perfect to pair with colorful skirts and dresses, especially patterned ones. I love the long blazer look but it's also smart to have a shorter blazer that falls at the hip which is why I've also chosen this Aqua Shirred Blazer in White (pictured right, $98 at Bloomingdales). The shirred 3/4 sleeves make this little blazer airy and light over your spring wardrobe.
