Ever since I figured out the secret behind color blocking, I've been using it to my advantage. This Old Navy Color Block Cardigan ($15, originally $30) features a Chanel-y palette of black and cream. I like how the light detailing calls attention to the right parts while the black disguises. The longer cut is perfect for wearing with skinnies and cool booties. Can you picture it? Also, isn't it a dead ringer for this Tory Burch cardigan? Double the discount.
