My college roommates all said they were coming to my closet if we had a barn dance. What can I say? I love button-down shirts.
One tip I've found for rolling the sleeves up is to roll them before you put the shirt on. Don't button the arm buttons or anything, just roll. The sleeves stay put so much better with this method, and has a tidy, yet relaxed look. Why did I not know this until last year?
I especially love a button down when transitioning into fall. They give a fallish look without being too warm. I like to wear them with shorts, too.
