When we think of casual days, we think of comfortable clothing. Here, we decided to mix a pair of light blue jeans with a warm and comfortable color-clock sweater by Casely-Hayford for those chill days, but if is warm, go ahead and pair it with a black and white striped shirt like this one by Neighborhood. Since, a lot of walking or running might be done, a pair of comfortable shoes is a most, here we paired this look with a pair of white sneakers by Moncler, along with a nice baseball cap to add a more sporty look this outfit.
