This laid-back pairing of a white long sleeve shirt and a short sleeve shirt is super easy to throw together without a second thought, helping you look seriously stylish and prepared for anything without spending too much time rummaging through your wardrobe. When this outfit is too much, dress it down by wearing a pair of white athletic shoes. So as you can see, this outfit is a really wonderful idea, especially for summer-to-fall weather, when the mercury is starting to drop.
