A light blue denim jacket and a crew-neck t-shirt are the kind of a foolproof off-duty ensemble that you so desperately need when you have no time to pull together a look. And if you need to easily class up your outfit with one single item, why not finish with a pair of blue suede pumps? So as you can see, this combo is a really good choice, especially for transeasonal weather, when the mercury is starting to drop.
