One of my favorite items in my closet is the button down blouse. A tried and true staple for me, it instantly adds a sense of polish, and yet still cool. I find it to be one of the most versatile articles of clothing. Since I'm such a fan of color and pattern, this blouse grabbed my attention immediately! You could wear it with anything. Bonus: it has navy, the it color for fall. Old Navy also has a great shirt that's similar. I think I like it more with the relaxed rolled sleeves and double pockets.
