Button-up shirts are one of my favorite things to wear. I was obsessed with them in college, and I think it's starting to happen again. Chambray is the most popular type of button-up right now. That's fine with me because they are so comfortable. I like pairing it with jeans in a contrasting color. Blue and white is the perfect combo for summer. Altogether it's fresh, effortless and the perfect off-duty look!
