A white button up should be in every fashionista's closet. This basic white shirt can be dressed up with a skirt and pumps for the office or even paired with shorts and jeans for a night out. It can be conservative or very very sexy by just unbuttoning one button. A form fitted white button up can be tucked in or be put under a cardigan. I have a couple in my closet because I really get a lot of wear out of them. You can never go wrong with a crisp white button up.
Here's how I rocked mine a while back for dinner and a movie with my bestie. I just paired it with some express boyfriend jeans and some oxfords. I think it was a hit.
